JavaScript Symbol split property is used to specify the method that splits a string at the indices that match a regular expression. This property is called by the String.split() method.
Syntax:
[Symbol.split](string)
Property attributes: It accepts a “String” which is not Writable, Enumerable, and Configurable.
Return value: It returns a string that is split from the given expression.
Below examples illustrate the Symbol split property in JavaScript:
Example 1: In this example, we will split the string and add (“”) in it.
Javascript
class Split1 {
constructor(value) {
this .value = value;
}
[Symbol.split](string) {
const index = string.indexOf( this .value);
return "'" + string.substr(0, index) + "' '" +
this .value + "' '" + string.substr(index + this .value.length) + "'" ;
}
}
console.log( 'GeeksforGeeks' .split( new Split1( 'for' )));
console.log( 'Geeks1Geeks2Geeks3Geeks4' .split( new Split1( 'Geeks' )));
|
Output:
"'Geeks' 'for' 'Geeks'"
"'' 'Geeks' '1Geeks2Geeks3Geeks4'"
Example 2: In this example, we will split the string and add (_) in it.
Javascript
class Split1 {
constructor(value) {
this .value = value;
}
[Symbol.split](string) {
const index = string.indexOf( this .value);
return "_" + string.substr(0, index) + "__" +
this .value + "__" + string.substr(index + this .value.length) + "_" ;
}
}
console.log( 'GeeksforGeeks' .split( new Split1( 'for' )));
console.log( 'Computer Science Portal' .split( new Split1( ' ' )));
|
Output:
_Geeks__for__Geeks_
_Computer__ __Science Portal_
