The split() method in JavaScript

Question: The split() method in JavaScript has What does it do?

Answer:

The split() method is used to split a string into a string array according to the specified delimiter.

Usage:

<code>str.split(separator, limit)</code>

• separator: Separator, can be any character, string or regular expression. If omitted, it defaults to an empty string, i.e. split on each character.
• limit: Optional, specifies the maximum length of the returned array. If not specified, the entire string is split.

Return results:

The split() method returns an array containing split string elements. If limit is less than the number of occurrences of the delimiter in the string, the array contains only limit elements.

Example:

<code>const str = "Hello, world!";

// 按空格拆分
const arr1 = str.split(" ");  // ["Hello,", "world!"]

// 按逗号拆分
const arr2 = str.split(",");  // ["Hello", " world!"]

// 按正则表达式拆分
const arr3 = str.split(/\s+/, 2);  // ["Hello", "world!"]</code>

Note: The

• split() method does not modify the original string.
• If the delimiter does not exist in the string, returns an array containing the entire string.
• If the separator is an empty string, returns an array containing each character.
