/m{X}/
or
new RegExp("m{X}")
Syntax with modifiers:
/\m{X}/g
or
new RegExp("m{X}", "g")

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(); |
