Introduction To JavaScript
JavaScript is a lightweight, cross-platform, and interpreted scripting language. It is well-known for the development of web pages, many non-browser environments also use it. JavaScript can be used for Client-side developments as well as Server-side developments. JavaScript contains a standard library of objects, like Array, Date, and Math, and a core set of language elements like operators, control structures, and statements.
Advantages of JavaScript
The merits of using JavaScript are −
- Less server interaction − You can validate user input before sending the page off to the server. This saves server traffic, which means less load on your server.
- Immediate feedback to the visitors − They don’t have to wait for a page reload to see if they have forgotten to enter something.
- Increased interactivity − You can create interfaces that react when the user hovers over them with a mouse or activates them via the keyboard.
- Richer interfaces − You can use JavaScript to include such items as drag-and-drop components and sliders to give a Rich Interface to your site visitors.

function sides(literals, ...expressions) {
const [area, perimeter] = expressions; // ES6 destructuring
const s1 = (perimeter + Math.sqrt(Math.pow(perimeter, 2) - 16 * area)) / 4;
const s2 = (perimeter - Math.sqrt(Math.pow(perimeter, 2) - 16 * area)) / 4;
return [s1, s2].sort();
}
