One common method is to use arr.replace(/xxx/g, "yyy"). However, a problem arises when the original string is "***", as the /* turns the code into a comment. How can I preserve the "***" while still being able to replace it?
Input
let arr = ["***"]
arr.replace(/***/g, "yyy")
Output
let arr = ["yyy"]
This represents the expected outcome.
To escape the asterisk symbol using a backslash and match exactly 3 characters, you can use {count} in your regex pattern. To work with the array, utilize .map() to create a new copy with the replaced strings.
function replaceThreeChars(str) {
return str.replace(/\*{3}/g, "yyy");
}
let arr = ["***"];
let updatedArr = arr.map(string => replaceThreeChars(string));
