description: >
The searchValue is observed before ToString(this value) and ToString(replaceValue)
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).
