esid: sec-string.prototype.replaceall
description: >
  A RegExp searchValue's Symbol.replace can be called instead of the next steps of replaceAll
info: |
  String.prototype.replaceAll ( searchValue, replaceValue )

  1. Let O be RequireObjectCoercible(this value).
  2. If searchValue is neither undefined nor null, then
    a. Let isRegExp be ? IsRegExp(searchString).
    b. If isRegExp is true, then
      i. Let flags be ? Get(searchValue, "flags").
      ii. Perform ? RequireObjectCoercible(flags).
      iii. If ? ToString(flags) does not contain "g", throw a TypeError exception.
    c. Let replacer be ? GetMethod(searchValue, @@replace).
    d. If replacer is not undefined, then
      i. Return ? Call(replacer, searchValue, « O, replaceValue »).
  3. Let string be ? ToString(O).
  4. Let searchString be ? ToString(searchValue).
