What is JavaScript?
JavaScript is a programming language that enables you to create interactive websites. It is a client-side language, which means that the code runs in the user’s browser. This makes it a very powerful tool for creating dynamic and responsive websites.
What are the basics of JavaScript?
JavaScript is a case-sensitive language. This means that uppercase and lowercase letters are treated as different letters. The language has three main data types: strings, numbers, and Booleans. Strings are text, numbers are just numbers, and Booleans are either true or false.
JavaScript also has a number of built-in functions, which are special pieces of code that can be used to do specific tasks. For example, the “alert” function displays a message in a pop-up window.
How do I write JavaScript code?
JavaScript code is written between two sets of curly braces, { and }. Everything that is written between the braces is treated as JavaScript code.
How do I run JavaScript code?
JavaScript code can be run in a number of ways. The most common way is to use a web browser such as Chrome, Firefox, or Safari. Simply open up the web browser and type in the address of the website that you want to visit. Then click on the “JavaScript” tab in the Developer Tools panel. This will open up the JavaScript code editor, where you can type in your code and run it.
Another way to run JavaScript code is to use a code editor such as Atom or Sublime Text. These editors have a built-in JavaScript interpreter, which means that you can type in your code and run it without having to use a web browser.
