Quick Reference
The String split() method splits a string into an array of substrings, and returns a new array, without changing the original string. If (‘ ‘) is used as separator, the string is split between words.
<!-- html element to place output -->
<p id="my_output"></p>
Example 1
// variables
let text = 'Hello world and the rest of the universe';
let my_result = text.split(' '); // split the entire string
// output to the HTML element
document.getElementById('my_output').innerHTML = my_result;
Example 2
// variables
let text = 'Hello world and the rest of the universe';
let my_result = text.split(' ', 3); // split only the first three words of the string
// output to the HTML element
document.getElementById('my_output').innerHTML = my_result;
Output
Example 1
Hello,world,and,the,rest,of,the,universe
Example 2
Hello,world,and
Syntax
string.split(separator, limit)
Parameters
| Parameter | Description |
|---|---|
| separator | A string or regular expression to use for splitting; if omitted, an array with the original string is returned |
| limit | An integer that limits the number of splits; items after the limit are excluded |
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.

JAVASCRIPT NOTES:
- When using JavaScript, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
- JavaScript is a case-sensitive language; firstName is NOT the same as firstname
- Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
- JavaScript variables must begin with a letter, $, or _
- JavaScript variables are case sensitive (x is not the same as X)
