Example 5: split() javascript

Example 6: javascript split regex

str.split(separator/*, limit*/)

/*Syntax explanation -----------------------------
Returns an array of strings seperated at every 
point where the 'separator' (string or regex) occurs. 
The 'limit' is an optional non-sub-zero integer. 
If provided, the string will split every time the 
separator occurs until the array 'limit' has been reached.
*/

//Example -----------------------------------------
const str = 'I need some help with my code bro.';

const words = str.split(' ');
console.log(words[6]);
//Output: "code"

const chars = str.split('');
console.log(chars[9]);
//Output: "m"

const limitedChars = str.split('',10);
console.log(limitedChars);
//Output: Array ["I", " ", "n", "e", "e", "d", " ", "s", "o", "m"]

const strCopy = str.split();
console.log(strCopy);
//Output: Array ["I need some help with my code bro."]
