The Symbol.split property in JavaScript is a well-known symbol which is used to specify the method that splits a string at the indices that match a regular expression. This function is called by the String.prototype.split() method.

[Symbol.split](string)

Return value: It returns a string that split from the given expression.
Below examples illustrate the Symbol.split property in JavaScript:
Example 1:
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:
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)+"_"; }}document.write('GeeksforGeeks'.split(new Split1('for')));document.write("<br>");document.write('Computer Science Portal'.split(new Split1(' '))); |
Output:
_Geeks__for__Geeks_ _Computer__ __Science Portal_
