replacing a string with multiple $ symbol in javascript

Question

I am trying to replace a string with multiple $ symbol in JavaScript using replace function. But all of the $ symbols are not getting written.

For eg:

var a = "xyz";
a = a.replace("xyz", "$$$");
console.log(a)

Output:

$$

The `$` character is special in replacement strings. You have to use two `$` characters for every one you actually want. — Pointy, Jun 26 '18 at 14:33

The $ symbol has special meaning when used inside String.replace. You can escape it by doubling it:

var a = "xyz";
a = a.replace("xyz", "$$$$$$");
console.log(a)

but even for "$$$$$" (5 dollar symbols) it prints "$$$" (3 dollar symbols) – coder Jun 26 '18 at 15:32
Yes. To be more precise, the $ symbol needs to be followed by certain characters e.g. digits or $ symbol to have an effect (see doc). The 5th $ symbol in your example is not substituted and displayed as-is. – Salman A Jun 26 '18 at 17:31

$ is a special character. so you have to use additional $ for each of them

var a = "xyz";
a = a.replace("xyz", "$$$$$$");
console.log(a)
