Typescript `replaceAll` Function not found

Programming

My two-year-old solution to the Pangram exercise in Typescript fails to compile today using the online editor because of the String.replaceAll function.

This is the error:

pangram.ts(4,6): error TS2550: Property 'replaceAll' does not exist on type 'string'. Do you need to change your target library? Try changing the 'lib' compiler option to 'es2021' or later.

Is this expected? Has something changed in the test runner? I don’t see any way to change any compiler options–would I need to change my code? (For what it’s worth, MDN characterizes the function as “Baseline Widely available” (String.prototype.replaceAll() - JavaScript | MDN)

Here’s my solution:

export function isPangram(value: string): boolean {
  return value
    .toLowerCase()
    .replaceAll(/[^a-z]/g, '')
    .split('')
    .reduce<string[]>((acc, char) => {
      if (acc.indexOf(char) < 0) acc.push(char);
      return acc;
    }, [])
    .length == 26;
}
