I need an alternative of replaceAll method, as it was added in ES2021/ES12.


let a = "xxxx-x[email protected]";
a = a.replace("xxxx-", "");
console.log(a);
output

// Actual
[email protected] 
// Required
[email protected]

You can do it via regular expression: use the /g (“match globally”) modifier with a regular expression argument to replace if you are assigning a RegExp directly


let a = "[email protected]";
a = a.replace(/xxxx-/g, "");

if you want to pass RegExp with some variable


let a = "[email protected]";

const code = 'xxxx';
const key = new RegExp(`${code}-`,"g");
a = a.replace(key, "");

You can not update value again in const.
