The split() method in JavaScript is used to split a string into an array of substrings based on a specified separator.
String split() Method Syntax:
str.split(separator, limit);- separator: It is used to specify the character, or the regular expression, to use for splitting the string. If the separator is unspecified then the entire string becomes one single array element. The same also happens when the separator is not present in the string. If the separator is an empty string (“”) then every character of the string is separated.
- limit: Defines the upper limit on the number of splits to be found in the given string. If the string remains unchecked after the limit is reached then it is not reported in the array.
Return value:
This function returns an array of strings that is formed after splitting the given string at each point where the separator occurs.
String split() Method Example:
Here is the basic example of the split() method.
JavaScript
// JavaScript Program to illustrate split() function function func() {
//Original string
let str = 'Geeks for Geeks'
let array = str.split("for");
console.log(array);
}func(); |
Output
[ 'Geeks ', ' Geeks' ]
Explanation:
- JavaScript program defines function func() splitting string ‘Geeks for Geeks’ using “for” as separator.
- Resulting array [“Geeks “, ” Geeks”] is logged to console.
String split() Method Example:
Here, the function split() creates an array of strings by splitting str wherever ” ” occurs.
JavaScript
// JavaScript Program to illustrate split() functionfunction func() {
//Original string
let str = 'It iS a 5r&e@@t Day.'
let array = str.split(" ");
console.log(array);
}func(); |
Output
[ 'It', 'iS', 'a', '5r&e@@t', 'Day.' ]
Explanation:
- The string ‘It iS a 5r&e@@t Day.’ is split into an array using a space as the separator.
- Resulting array: [“It”, “iS”, “a”, “5r&e@@t”, “Day.”].
