Welcome to JavaScript!

JavaScript, or JS, is a very useful computer language. It was first made to help websites do more than just show information. Now, JavaScript can do a lot more, both on websites and on servers with something called Node.js.

What is JavaScript?

JavaScript was made by a company named Netscape in the 1990s. It was meant to make websites better by letting them react to what you do, like clicking buttons or filling out forms. Now, almost all websites use JavaScript to work better and do more things.

What Can JavaScript Do?

• Change on the Fly: JavaScript lets you change websites while you're looking at them, without having to load a new page.
• Wait and Work: It can do things without stopping everything else. This is great for talking to other computers like when a website checks your password.
• Simple Rules: It doesn't have strict rules for how you write it, which makes it easier to learn and use.

JavaScript on Websites

When you use the internet, JavaScript is working in your browser (like Chrome or Firefox). It helps websites talk to you better by changing things on the page or checking the information you put in.

JavaScript on Servers

JavaScript also works on servers thanks to Node.js. A server is a computer that sends you web pages when you ask for them. Node.js lets JavaScript run on these servers.

Why Node.js is Great:

• Same Language Everywhere: You can use JavaScript for both the parts of the website you see and the parts on the server. This makes it easier to build everything.
• Fast and Strong: Node.js is good for tasks that need to talk a lot with other computers without slowing down.
• Lots of Tools: Node.js comes with npm, which has tools that you can easily add to your projects.
