You'll certainly be better than many of your peers when coding JavaScript. After you've completed at least projects on this list of JavaScript projects for beginners, you can say without a doubt that you've built at least small to medium sized, working applications.
Technical recruiters will love to hear this when they are looking to fill junior to mid-level JavaScript Developer roles. Completing at least projects allows you to slow down, which further allows you to see different JavaScript techniques. If you want to become an expert JavaScript Developer, you've got do more than just say you're a JavaScript developer.
You have to show you're a JavaScript Developer. Having a portfolio of JavaScript projects that you put together carries much more weight than your word. After completing at least of these different JavaScript projects for beginners, you'll undoubtedly be a better developer. You'll find that the implementations that used to take you hours to remember now takes you only a few minutes. You'll use many different JavaScript patterns and begin to see how different implementations can speed up your coding.
Let's minimize your Stack Overflow searching every three lines of code and get you more productive! Let's face it, not everyone will follow through with this challenge. Because of that, you'll be a rare exception, able to distinguish yourself from the masses. If you can code these JavaScript projects for beginners, and are able to show them off, fellow coders will be super impressed at your dedication to your craft!
The time it takes to complete all the projects will vary based on your JavaScript skills and your schedule. If you're a true beginner, I recommend you start with The Modern JavaScript course before beginning here. Andrew's course alone is over 29 hours! Which means it'll likely take you a total of 60 hours just to get through his course.
But once you complete his course, you can return here. Then, you'll need about an hour to several hours per each JavaScript project above. Some projects are simple JavaScript projects for beginners and will take about 10 minutes and others can take up to an entire weekend! But don't fear, even if it takes you six months to get through all of these projects, this is only a small period of your life relative to the time you'll spend for the rest of your life as a full-time JavaScript developer.
The first thing you should do is go to my source code on github and see how I completed the project. If you still need to see some sort of video solution, follow the link to the course, sign up which will give you access to all the instructor's projects , and then watch the instructor's video solution. Luckily, I found most of the courses on Udemy, a low-cost online course platform, or on other free platforms. Udemy is known to have many of their courses at great discounts, especially during United States' holiday weekends.
If you already know a bit of JavaScript but want to learn more , and you want to have a better grasp into how to put all its pieces together, I'd strongly encourage you to begin with Andrew Mead's, The Modern JavaScript Bootcamp.
In it, you'll not only cover pretty much everything you need to know about JavaScript including the new ES6 features , but you'll get to build 3 great JavaScript apps in the process. His course is completely project based! And as a capstone, he challenges you to build your own recipe app just like this JavaScript Recipe App Project!
The reason why I strong recommend Andrew's course is he's the only JavaScript instructor I've come across that consistently points out where to find a specific feature of JavaScript using the MDN JavaScript documentation. This in and of itself is helpful, especially when you need to constantly remind yourself how different features and methods of the language works.
Additionally, he provides a great reference guide that explains everything he teaches in his course. For the most part, I watched his intro and then built the JavaScript projects out myself. I highly recommend you do the same for all of the projects! The first 18 JavaScript projects above focuses only on coding the JavaScript functionality for front-end projects. These projects cover a lot of core JavaScript. Projects 15, 16, and 17 focuses heavily on JavaScript Object projects.
Next, in project 19, you'll build out the full functionality of a car dealership website using features of the JavaScript language that were introduced in ES6.
Once you complete the first 27 projects, you can move on to the 27 different beginner JavaScript projects that I found in Bluelime's JavaScript Beginner Projects course.
Most of these will be pretty simple JavaScript projects if you've finished the first 27 JavaScript projects. You should be able to breeze through each in a few hours since they use features that you've seen time and time again in the previous 54 beginner JavaScript projects.
These projects are super fun! And if the previous beginner projects are not enough, projects above come from Wes Bos's JavaScript30 course. JavaScript30 is a mix of JavaScript instructions and projects, so despite the name, not all of the 30 videos in his series are projects. But, he does teach some cool stuff that you may have not learned. There you have it! Over different JavaScript projects for beginners and even a few for intermediate JavaScript developers.

For example, even though this Boolean object is explicitly set to false, it evaluates to true and the code is executed:. To convert a non-boolean value to a boolean, use Boolean as a function rather than as an object:. This section gives a brief introduction to the concept and usage of callback functions in JavaScript. The first thing we need to know is that in JavaScript, functions are first-class objects.
As such, we can work with them in the same way we work with other objects, like assigning them to variables and passing them as arguments into other functions. A function that accepts other functions as arguments is called a higher-order function , which contains the logic for when the callback function gets executed. In the above example, createQuote is the higher-order function, which accepts two arguments, the second one being the callback.
The logQuote function is being used to pass in as our callback function. When we execute the createQuote function 1 , notice that we are not appending parentheses to logQuote when we pass it in as an argument.
This is because we do not want to execute our callback function right away, we simply want to pass the function definition along to the higher-order function so that it can be executed later.
Also, we need to ensure that if the callback function we pass in expects arguments, we supply those arguments when executing the callback 2. In the above example, that would be the callback myQuote ; statement, since we know that logQuote expects a quote to be passed in. Additionally, we can pass in anonymous functions as callbacks. The below call to createQuote would have the same result as the above example:. Based on the above example, the below function will behave in exactly the same manner.
Most of the time we are creating programs and applications that operate in a synchronous manner. In other words, some of our operations are started only after the preceding ones have completed.
These situations are where callback functions come in handy. In the above example, we make a mock request to a server. After 5 seconds elapse, the response is modified and then our callback function getResults gets executed. But we could simulate the functionalities of a class by taking advantage of the prototypal nature of JavaScript. This section assumes that you have a basic understanding of prototypes. Like in any other programming language, you can now use the class keyword to create a class.
Most often, some properties and methods have to be hidden to prevent access from outside the function. With classes, to obtain this functionality, one way to do this is by using symbols. Symbol is a new built-in type of JavaScript, which can be invoked to give a new symbol value. Every Symbol is unique and can be used as a key on object.
So one use case of symbols is that you can add something to an object you might not own, and you might not want to collide with any other keys of object. Therefore, creating a new one and adding it as a property to that object using symbol is the safest.
Also, when symbol value is added to an object, no one else will know how to get it. A closure is the combination of a function and the lexical environment scope within which that function was declared.
Closures are a fundamental and powerful property of Javascript. This environment consists of any local variables that were in-scope at the time the closure was created. This allows Javascript to emulate private methods that are found in other programming languages.
Private methods are useful for restricting access to code as well as managing your global namespace. Well, think about what bankAccount is returning. It actually returns an Object with a bunch of functions inside it, and yet when we call account. Javascript did not have a concept of block-scoped variables. Meaning that when defining a variable inside a for-loop, for example, this variable was visible from outside the for-loop as well.
So how can closures help us solve this problem? Closures can help us solve this issue by creating a snapshot of the environment the function was in when it was created, preserving its state. There are also many functions forEach and entire libraries lodash. They can certainly boost your productivity, however it remains extremely important to have knowledge of all these issues when attempting to create something big.
Unlike many other languages, Javascript does not have a mechanism which allows you to create encapsulated instance variables within an object. Having public instance variables can cause a lot of problems when building medium to large programs.
However with closures, this problem can be mitigated. Thus, making them effectively private. Closures can also help you manage your global namespace to avoid collisions with globally shared data.
Usually, all global variables are shared between all scripts in your project, which will definitely give you a lot of trouble when building medium to large programs. This is called the module pattern, it uses an immediately invoked function expression which exports only certain functionality to the outside world, significantly reducing the amount of global references. Programmers use comments to add hints, notes, suggestions, or warnings to their source code; they have no effect on the actual output of the code.
Comments can be very helpful in explaining the intent of what your code is or should be doing. It is always best practice when starting out to comment more often than not, as it can help those reading your code to understand what exactly your code is intending to do. For example:. JavaScript has both strict and type—converting comparisons.
The equality operator first converts operands that are not of the same type, then strictly compares them to one another. The inequality operator evaluates to true if both operands are not equal.
If the operands are not the same type, it will try to convert them to the same type before making the comparison. The identity or strict equality operator returns true if both operands are strictly equal in terms of value and type.
The non-identity or strict inequality operator returns true if both operands are not strictly equal in terms of value or type. The greater than operator returns true if the operand on the left is greater than the one on the right. The greater than or equal operator returns true if the operand on the left is greater than or equal to the one on the right. The less than operator returns true if the operand on the left is less than the one on the right. The less than or equal operator returns true if the operand on the left is less than or equal to the one on the right.
Form validation used to occur at the server, after the client had entered all the necessary data and then pressed the Submit button. If the data entered by a client was incorrect or was simply missing, the server would have to send all the data back to the client and request that the form be resubmitted with correct information.
This was really a lengthy process which used to put a lot of burden on the server. Form validation generally performs two functions:. First of all, the form must be checked to make sure all the mandatory fields are filled in. It just requires a loop through each field in the form to check for data. Secondly, the data that is entered must be checked for correct form and value. Your code must include appropriate logic to test the correctness of the data. First let us see how to do a basic form validation.
In the above form, we are calling validate to validate data when the onsubmit event is occurring. The following code shows the implementation of this validate function.
Now we will see how we can validate our entered form data before submitting it to the web server. The following example shows how to validate an entered email address. A less commonly used constraint is the pattern attribute that takes a JavaScript regular expression. The if statement executes a statement if a specified condition is true. If the condition is false , another statement can be executed using the else statement.
Multiple if This specifies a new condition to test and can be repeated to test multiple conditions, checking until a true statement is presented to execute.
Note: If you want to execute more than one statement in the if , else or else if part, curly braces are required around the statements:.
