Return abrupt from ToNumber(next).

info: |
|
||
String.fromCodePoint ( ...codePoints )
|
||
|
||
1. Let result be the empty String.
|
||
2. For each element next of codePoints, do
|
||
a. Let nextCP be ? ToNumber(next).
|
||
b. If nextCP is not an integral Number, throw a RangeError exception.
|
||
c. If ℝ(nextCP) < 0 or ℝ(nextCP) > 0x10FFFF, throw a RangeError exception.
|
||
d. Set result to the string-concatenation of result and UTF16EncodeCodePoint(ℝ(nextCP)).
|
||
3. Assert: If codePoints is empty, then result is the empty String.
|
||
4. Return result.
