Introduction to different JavaScript string splitting methods

There are many ways to split and process js strings. Some common methods will be introduced below and specific code examples will be provided.

1. split() method:
   This is a built-in method of the js string object, used to split the string into a string array. It accepts a split string as argument and returns an array consisting of the split substrings.

Code example:

let str = "hello world";
let arr = str.split(" ");
console.log(arr); // 输出 ["hello", "world"]

2. split() method uses regular expressions:
   split() method can also use regular expressions as parameters for splitting.

Code example:

let str = "hello123world";
let arr = str.split(/d+/);
console.log(arr); // 输出 ["hello", "world"]

3. slice() method combined with loop processing:
   If you want to split the string according to a fixed length, you can combine it with the slice() method And loop to achieve.

Code example:

let str = "helloworld";
let arr = [];
let length = 3;
for(let i = 0; i < str.length; i += length) {
  arr.push(str.slice(i, i+length));
}
console.log(arr); // 输出 ["hel", "low", "orl", "d"]

4. substring() method combined with loop processing:
   substrin() method is similar to slice() method and can be used to convert strings Divide according to fixed length.

Code example:

let str = "helloworld";
let arr = [];
let length = 3;
for(let i = 0; i < str.length; i += length) {
  arr.push(str.substring(i, i+length));
}
console.log(arr); // 输出 ["hel", "low", "orl", "d"]

5. Use regular expression match() method:
   match() method returns an array composed of matching results, through regular expression Formula to split strings.

Code examples:

let str = "hello world";
let arr = str.match(/w+/g);
console.log(arr); // 输出 ["hello", "world"]

The above are some common methods and code examples for splitting and processing js strings. You can choose the appropriate method to process strings according to actual needs.
