JavaScript Tutorial for Beginners - var, let const?

In this series we will be looking at ES6 features, along with some functional programming concepts, and later in the series looking at how JavaScript deals with garbage collection, how the call stack model works, how JavaScript handles its compiling phases, and lastly, how the compiler works itself.

My knowledge of JavaScript comes from years of writing JavaScript code, but truly understanding how JavaScript actually works comes from watching videos and reading books. I’d like to tip my hat to the following people: Will Sentance, Kent Dodds, Kyle Simpson, and many others in the JS community who produce content.

It’s important to be a lifelong learner and a lot of my knowledge on these topics comes from the content that these people produce, so if you get chance, check them out as they have a better understanding on this stuff than I do!

P.S. I named this series to begin with ES6, then I renamed it to JavaScript as I want to cover the entire language properly (or at least try)!

Watch this JavaScript tutorial for beginners to learn JavaScript basics in one hour.
avaScript is one of the most popular programming languages in 2019. A lot of people are learning JavaScript to become front-end and/or back-end developers.

I’ve designed this JavaScript tutorial for beginners to learn JavaScript from scratch. We’ll start off by answering the frequently asked questions by beginners about JavaScript and shortly after we’ll set up our development environment and start coding.

Whether you’re a beginner and want to learn to code, or you know any programming language and just want to learn JavaScript for web development, this tutorial helps you learn JavaScript fast.

You don’t need any prior experience with JavaScript or any other programming languages. Just watch this JavaScript tutorial to the end and you’ll be writing JavaScript code in no time.

If you want to become a front-end developer, you have to learn JavaScript. It is the programming language that every front-end developer must know.

You can also use JavaScript on the back-end using Node. Node is a run-time environment for executing JavaScript code outside of a browser. With Node and Express (a popular JavaScript framework), you can build back-end of web and mobile applications.

If you’re looking for a crash course that helps you get started with JavaScript quickly, this course is for you.

JavaScript Variables: var and let and const

There are three ways to create variables in a JavaScript application: using var, using let, or using const. This will not be a post trying to convince you which one you should use, or arguing about what is best. It’s just good to know about the differences and what it means when you use the different options. But hopefully by the end of all this you’ll be comfortable with the three options and can make a decision for your team that will suit your needs. To get the most out of this post, it is best if you understand variable scope, which we covered in this post previously.

Declaring A Winner Between JavaScript's var, let And const

When ECMAScript 6 (also known as ECMAScript 2015) was released a collection of new APIs, programming patterns and language changes became a standard. Since ES6 started gaining browser and nodejs support developers are wondering if they should stop using the traditional var to declare variables.
ES6 introduced two new ways to declare variables, let and const.

var - has function level scoping and can change the value reference
let - has block level scoping and can change the value reference
const - has block level scoping but cannot change the value reference
Both provide better block scoping that var. const differs from let because the immediate value cannot be changed once it is declared.
Variables declared using var are function scoped, which has led to confusion to many developers as they start using in JavaScript.
