What is Split function?

First of all, we are going to explain the concept of split function.
As we have mentioned above, you split string into the substrings.
In order to do so, you have to use specific separators.
As a result, you will get an array.
The major variants of this methodology are:
String[] split(String regex): By using this method, you will get an array of strings once you split the input string which is based on delimiting the regular expression.
String[] split(String regex, int limit): You will find only one difference between these two variations.
The difference is that it will limit the number of strings which are retuned after the split up.

Syntax of split function:

Following is the syntax of split function which you can use in your codes:

Parameters of split function:

  • StringObj: The first parameter of split function is required. Here, we would like to add that the object is not modified by the split method.
  • Separator: This is optional. This is a regular expression object which is used in order to identify the characters for the purpose of separating the string.
  • Limit: Limit is also optional. The role of limit is to limit the number of elements which are supposed to be returned in the array.

Example

The following case demonstrates the use of the split method.
JavaScriptCopy

var s = " Every cloud has a silver lining. ";  
var ss = s.split(" ");  
for (var i in ss) {  
    document.write(ss[i]);  
    document.write("<br/>");  
}  
// Output:   
// Every 
//has 
//a 
//silver 
//lining
