This is the first article of the Javascript Starwars series and guess what the topic is Javascript itself.

What is Javascript?

Javascript is a scripting language, which was created by Brendan Eich in 1995 to make webpages alive. Programs here are called “Scripts”.

Funfact: Do you know inital name of JavaScript was “LiveScript”. It was renamed to javascript as “Java” was much popular that time so js was seen as a younger brother of Java. Although with no relationship :)

What `can` Javascript do (in browsers)?

Add new HTML to a page and manipulate the styling of the page.
Set/Get Cookies to the browser
Have access to Local storage of the browser
Can receive/send data by hitting API calls like AJAX, fetch, etc.
Read on user actions like user clicks, scrolls, keypress etc.

What `can't` Javascript do (in browsers)?

Cross-origin resource sharing- when we have to share/get resources from other resources to our website we face a CORS error because the browser by default doesn’t allow 3rd party resource sharing
Interaction directly with OS function is prohibited in javascript. Like files directly user cannot do although with special permissions only

Should I learn JavaScript in `2023`?

The short answer is definitely. JS is like the Mother of the Web and Frontend. Also for a junior dev, it is ok to jump over to Frameworks like react or Next.js and skip in-depth js, but at a certain level in your career when you become a senior dev, you have to deal with js concepts.
