JavaScript RegExp {X,Y} QuantifierThe RegExp m{X, Y} Quantifier in JavaScript is used to find the match of any string that contains a sequence of m, X to Y times where X, Y must be numbered.
Syntax:
/m{X, Y}/
or
new RegExp("m{X, Y}")
Syntax with modifiers:
/\m{X, Y}/g
or
new RegExp("m{X}", "g")
Example 1: This example matches the presence of the word between [a-g] of length 3 to 4 in the whole string.
Javascript
function geek() { let str1 = "GeeksforGeeeeks@_123_$"; let regex4 = /[a-g]{3,4}/gi; let match4 = str1.match(regex4); console.log("Found " + match4.length + " matches: " + match4);}geek(); |
Found 2 matches: Gee,Geee
Example 2: This example replaces the word ‘ee’ or ‘eee’ with ‘$’.
Javascript
function geek() { let str1 = "ee@128GeeeeK"; let regex4 = new RegExp("e{2,3}", "gi"); let replace = "$"; let match4 = str1.replace(regex4, replace); console.log(" New string: " + match4);}geek(); |
