| Behavior for input array of Strings, successful conversion |
| info: | |
| 22.2.4.4 TypedArray ( object ) |
| |
| This description applies only if the TypedArray function is called with at |
| least one argument and the Type of the first argument is Object and that |
| object does not have either a [[TypedArrayName]] or an [[ArrayBufferData]] |
| internal slot. |
| |
| ... |
| 8. Repeat, while k < len |
| ... |
| b. Let kValue be ? Get(arrayLike, Pk). |
| c. Perform ? Set(O, Pk, kValue, true). |
| ... |
| |
| 9.4.5.5 [[Set]] ( P, V, Receiver) |
| |
| ... |
| 2. If Type(P) is String and if SameValue(O, Receiver) is true, then |
| a. Let numericIndex be ! CanonicalNumericIndexString(P). |
| b. If numericIndex is not undefined, then |
| i. Return ? IntegerIndexedElementSet(O, numericIndex, V). |
| ... |
| |
| 9.4.5.9 IntegerIndexedElementSet ( O, index, value ) |
| |
| ... |
| 5. If arrayTypeName is "BigUint64Array" or "BigInt64Array", |
| let numValue be ? ToBigInt(value). |
| ... |
| |
| ToBigInt ( argument ) |
| |
| Object, Apply the following steps: |
| 1. Let prim be ? ToPrimitive(argument, hint Number). |
| 2. Return the value that prim corresponds to in Table [BigInt Conversions] |
| |
| BigInt Conversions |
| Argument Type: String |
| Result: |
| 1. Let n be StringToBigInt(prim). |
| 2. If n is NaN, throw a SyntaxError exception. |
| 3. Return n. |
