split() function splits a string into an array according to the specified delimiter. Usage: result = string.split(separator, limit), where separator is the separator and limit is the optional limit on the number of elements (no limit by default). Returns an array containing substrings, delimited by characters, regular expressions, or strings. If delimiter is empty, each character becomes an element. If the delimiter is not in the string, returns a single-element array containing the entire string. limit controls the number of elements in the returned array.

How to use split function in js

Usage of split function in JS

split() The function is a built-in JavaScript Function that splits a string into an array using a specified delimiter. It is widely used in string processing and text parsing.

Usage:

<code>var result = string.split(separator, limit);</code>

Where:

  • ##string: The string to be split.
  • separator: The separator used to split the string.
  • limit (optional): The maximum number of array elements after splitting. By default, limit is Infinity, which means the string will be split into any number of elements.

Return value:

split() The function returns an array containing substrings. If no delimiter is specified, the function uses the space character as the default delimiter.

Example:

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

// 按逗号分隔字符串
const result1 = str.split(","); // ["Hello", " World!"]

// 按空格分隔字符串,限制为 2 个元素
const result2 = str.split(" ", 2); // ["Hello,", "World!"]</code>

Note:

    The delimiter can be a single character, a regular expression, or other strings.
  • If the delimiter is an empty string, each character will become a separate element.
  • If the delimiter is not found in the string, the
  • split() function will return a single-element array containing the entire string. The
  • limit parameter allows controlling the number of elements in the split array. If limit is less than the number of occurrences of the delimiter in the string, the returned array will contain limit elements and the remainder will be discarded.
