`removeFirstTwo([1, 2, 3, 4, 5])` should be `[3, 4, 5]`

const testArrWORemoved_ = removeFirstTwo(testArr_);
assert(testArr_.every((e, i) => e === i + 1) && testArr_.length === 5);

`Array.slice()` should not be used.
```js
assert(!code.match(/slice/g));
assert(!code.match(/\.\s*slice\s*\(/));
```
Destructuring on `list` should be used.
You should use the rest syntax.
```js
assert(
__helpers
.removeWhiteSpace(code)
.match(/\[(([_$a-z]\w*)?,){1,}\.\.\.shorterList\]=list/i)
);
assert.match(code, /\.\.\./);
```
