JavaScript split() Function Guide

The split() function in JavaScript is used to divide a string into an array of substrings and then return that array. It requires a delimiter as a parameter, which is used to split the original string into multiple substrings and store them in the array.

Grammar:

string.split(separator, limit)

Explanation of parameters:

1. separator: specifies the delimiter, which can be either a string or a regular expression. If this parameter is omitted, the entire string will be split into an array of characters.
2. Limit: an optional parameter that specifies the maximum length of the array to be returned.

Original: 我们需要更多的时间来完成这项工作。

Paraphrased: We need more time to complete this task.

var str = "Hello,world,how,are,you";
var arr = str.split(",");
console.log(arr); // Output: ['Hello', 'world', 'how', 'are', 'you']

In the example above, we used a comma as a delimiter to split the original string into multiple substrings and store them in an array called arr.
