Before you start learning something new, it’s important to understand
exactly what it is and what it does. This is especially useful when it comes to
mastering a new programming language.
In simple terms, JavaScript is a programming language used to make websites
interactive. If you think about the basic makeup of a website, you have HTML,
which describes and defines the basic content and structure of the website, and
then you have CSS, which tells the browser how this HTML content should be
displayed determining things like color and font. With just HTML and CSS, you
have a website that looks good but doesn’t actually do much. JavaScript brings
the website to life by adding functionality.
JavaScript is responsible for elements that the user can interact with, such
as drop-down menus, modal windows, and contact forms. It is also used to create
things like animations, video players, and interactive maps.
If you’re having doubts about JavaScript, it’s important to know that, since its creation in 1995, JavaScript is pretty much everywhere on the web and that’s not likely to change any time soon. The most obvious reason for learning JavaScript is if you have hopes of becoming a web developer. Even if you haven’t got your heart set on a tech career, being proficient in JavaScript will enable you to build websites from scratch—a pretty useful skill to have in today’s job market!
Now you may wonder why this JavaScript became so popular, there are a few
different programming languages, and they didn’t become so popular. JavaScript
is a language that has a very wide range of usage. Knowing only JavaScript, you
are able to create an entire web application. Mobile app? Not a problem at
all, there are lots of frameworks for JavaScript which allow us to easily
create front-end of the application, like for example Angular, React.js,
Vue.js, and many more. To create back-end, you don’t need to learn a different
programming language; it’s enough to use a different framework like Node.js and
learn a little bit about databases and API. Also, JavaScript has a solution for
mobile applications. To create a mobile front-end, you can use a different
framework like React Native or Flutter or a different one.
In this case, no matter if you would like to create a web app or mobile app
or even a simple website, you can use JavaScript for all of this.
So, should you learn JavaScript? The answer is YES !
