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 vowelsAndConsonants(s) {
  const vowels = ["a", "e", "i", "o", "u"];
  const string = s.split("");
  let vowelArr = [];
  let consonantArr = [];
  for (let i = 0; i < string.length; i++) {
      ? vowelArr.push(string[i])
      : consonantArr.push(string[i]);
  for (let i = 0; i < vowelArr.length; i++) {
  for (let i = 0; i < consonantArr.length; i++) {
