Does anyone know this issue about replace function of javascript ? I only want to replace string.

"$$$AAA".replace("$$$AAA","$$$aaa");

Event using with regex it's getting same output.

"$$$AAA".replace(new RegExp(/\$\$\$AAA/, "gi"),"$$$aaa");

Output

$$aa

Expected

$$$aaa

It's strip out the first $

`$` sometimes has a special meaning in the replacement string. Use `$$` instead, for a literal `$` – CertainPerformance Feb 10 '20 at 03:28
so i need to add extra `$` before the string that start with `$`. hmm. so it's the rule of js. – Đặng Quốc Đạt Feb 10 '20 at 04:38
