JavaScript code is executed in your's web browser. When you visit a web page that contains JavaScript code, the code is executed as the page loads. JavaScript is an interpreted language, which means that it's not compiled into machine code like other programming languages. Instead, the JavaScript interpreter parses and executes the code as it runs.One of the benefits of interpreted languages is that they're usually easy to learn and use. JavaScript is a relatively simple language, making it good for beginners. However, its simplicity also means that it lacks some of the features and tools found in other programming languages.The JavaScript language provides features that allows developers to do things like:Keep values inside a variable. If you ask for a job title to be entered in a form field, it can store the name in a variable called “job title”Do operations on text pieces, which is referred to as strings. So if you have a  string called “Name:” it’s possible to ad a variable to the string and thereby create a text label; “Name: Jake”.It’s also possible to execute code when an event occurs on the website. This could be a click on a “Add to cart” button. When the button is clicked, it will perform an action where the product is added to the cart and updates an icon on the cart, that tells how many products are now in the cart.And the list continued with all the cool things you can do with JavaScript.
