Welcome to JavaScript Language!

For sure you have encountered before on the internet terms like: ‘Coding’, ‘Application’, ‘Developer’. You have been curious about how the code works, how an app is built, and how to be a developer. Well, this time let’s take things seriously. JavaScript itself is the main language that the web is built, and for this reason, it sets the order on the web. The first realization was on December 4, 1995.

By the way, a list of words that I wrote above, in the code editor can be written like this:

let terms = ['Coding', 'Application', 'Developer'];

…and this is called Array, and this Array can be included inside an Object like this:

let text = {
    language: "JavaScript",
    iamCurious: true,
    realization: 1995,
    terms: ['Coding', 'Application', 'Developer'],
}

The result of the code on the console will be:

console.log(text.iamCurious); // true
console.log(text.terms[2]); // Developer

Even if you don’t understand anything that is written above, this will be more interesting after you will start learning JS. This period of learning and looking into the language can take from 3 months to 1 year, depending on the time you will spend coding JS.

Why should I learn JavaScript and why is it so important in my programming career?

JavaScript is 1 of the 3 languages that all web developers must learn before starting their careers:

1. HTML to define the content of web pages.
2. CSS to specify the layout of web pages.
3. JavaScript to program the web pages.

More than 98% of all websites use JavaScript. JavaScript, CSS, and HTML work together to make up the user-facing elements of most websites and online applications. Like most other languages, JavaScript is upgraded every year (every June), with new code syntax, new methods (pre-made functions), and other improved techniques, due to feedback from corporates and programmers.

All versions of JavaScript are listed here:

• First conceiving of the language (1995)
• Real JavaScript ES1 ES2 ES3 (1997-1999)
• The First Main Revision was ES5 (2009)
• The Second Main Revision was ES6 (2015)
• Later Additions (2016 … 2020 … 2025 …)
