Javascript replace string with list from array

Question

I have a string that is a normal sentence. I need to replace the characters in the string if they are found in a given array. For example,

const arr = ["(model: Audi)", "(model: Kia)"];

if the string is:

"How is your (model: Audi) today?";

The result should be "How is your Audi today?".

Is there a way to do this with regex? I read somewhere that regex has better performance. I've tried looping thru the array then replacing the characters but I couldnt get it working and my solution would have nested loops due to the given string

If they all match that pattern, do you need the array at all? "How is your (model: Audi) today?".replace(/$[^:]+:\s([^$]+)\)/, '$1') — epascarello

const arr = ["(model: Audi)", "(model: Kia)"];
let string = "How is your (model: Audi) today?";
for (let data of arr){
  string = string.replace(data, data.split(": ")[1].replace(")",""))
}
console.log(string);

Well, this is the simplest I have managed to do.

However, I myself kind of consider it a bad solution.

Let me know if it helps at all...

const myString = "How is your (model: Audi) today?";
const arr = ["(model: Audi)", "(model: Kia)"];

arr.forEach(item => {
  const part = item.match(/\w+\)$/)[0];
  const subPart = part.substring(0, part.length - 1);

  if (myString.includes(item))
    console.log(myString.replace(item, subPart));
});
