var nameArr = names.split(',');
console.log(nameArr);
 
// Accessing individual values
alert(nameArr[0]); // Outputs: Harry
alert(nameArr[1]); // Outputs: John
alert(nameArr[nameArr.length - 1]); // Outputs: Alice
 
var str = 'Hello World!';
var chars = str.split('');

alert(chars[0]); // Outputs: H
alert(chars[1]); // Outputs: e

*
*/

const str = 'The quick brown fox jumps over the lazy dog.';
console.log(str.split(''));
console.log(str.split(' '));
console.log(str.split('ox'));
> Array ["T", "h", "e", " ", "q", "u", "i", "c", "k", " ", "b", "r", "o", "w", "n", " ", "f", "o", "x", " ", "j", "u", "m", "p", "s", " ", "o", "v", "e", "r", " ", "t", "h", "e", " ", "l", "a", "z", "y", " ", "d", "o", "g", "."]

> Array ["The quick brown f", " jumps over the lazy dog."]

Example 4: js split string

var myString = "Hello World!";

// splitWords is an array
// [Hello,World!]
var splitWords = myString.split(" ");

// e.g. you can use it as an index or remove a specific word:
var hello = splitWords[splitWords.indexOf("Hello")];
