Text Processing with JavaScript

split()

The split() method splits a string into substrings and returns them as an array. The first argument, which can be either a string or a regex, specifies the position at which the split should occur. The second argument limits the number of elements returned in the array. Here’s an example:

appendix/methods/methods_ex16.js

const str = "a b c";

console.log(str.split(" "));       // → ["a", "b", "c"]
console.log(str.split(/\s/, 2));   // → ["a", "b"]
