Literal dollar sign in a regular expression

Question

I am working with Canada (fr-CA) locale and trying to do following:

var str = "<dataset >{1}</dataset>";
var temp = "<set Cost x = '1,8M $' />";

str = str.replace(/\{1\}/g, temp);

OUTPUT:

"<dataset ><set Cost x = '1,8M  </dataset>" /></dataset>"

DESIRED OUTPUT:

"<dataset ><set Cost x = '1,8M $'" /></dataset>"

replace function is misunderstanding $' from '1,8M $' as an expression and hence
repeating in the output. Any ideas/workaround? Thank you for your time.

$' has a special meaning in the replacement string when using JS regular expressions: it inserts the portion of the string that follows the matched substring. To get a literal dollar sign in the replacement string, use $$.

See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace.

Could you just use the ascii code for dollar sign? $
