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('neveropen'.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('neveropen'.split(new Split1('for'))); console.log('Computer Science Portal'.split(new Split1(' '))); |
Output:
_Geeks__for__Geeks_ _Computer__ __Science Portal_
