The RegExp m{X} Quantifier in JavaScript is used to find the match of any string that contains a sequence of m, X times where X is a number.
Syntax:
/m{X}/
or
new RegExp("m{X}")
Syntax with modifiers:
/\m{X}/g
or
new RegExp("m{X}", "g")
Example 1: This example matches the presence of the word ‘ee’ in the whole string.
Javascript
function geek() { let str1 = "neveropen@_123_$" ; let regex4 = /e{2}/gi; let match4 = str1.match(regex4); console.log( "Found " + match4.length + " matches: " + match4); } geek(); |
Found 2 matches: ee,ee
Example 2: This example replaces the word ‘ee’ with the character ‘E’.
Javascript
function geek() { let str1 = "ee@128GeeeeK" ; let regex4 = new RegExp( "e{2}" , "gi" ); let replace = "E" ; let match4 = str1.replace(regex4, replace); console.log( " New string: " + match4); } geek(); |
New string: E@128GEEK
