How to Parse a String in JavaScript?

You can split a JavaScript string using the `split` method, which is part of the String prototype. In your case, since the string is formatted with hyphens (`-`), you can split it by specifying `’-‘` as the delimiter. Here’s how you can do it:

Using an Array

var coolVar = '123-abc-itchy-knee';
var array = coolVar.split('-');

console.log(array[0]); // '123'
console.log(array[1]); // 'abc'
console.log(array[2]); // 'itchy'
console.log(array[3]); // 'knee'

Using Separate Variables

var coolVar = '123-abc-itchy-knee';
var [var1, var2, var3, var4] = coolVar.split('-');

console.log(var1); // '123'
console.log(var2); // 'abc'
console.log(var3); // 'itchy'
console.log(var4); // 'knee'
