- Use Array.prototype.slice() twice to get the elements after the specified index and the elements before that.
- Use the spread operator (...) to combine the two into one array.
- If offset is negative, the elements will be moved from end to start.
//#Source https://bit.ly/2neWfJ2 const offset = (arr, offset) => [...arr.slice(offset), ...arr.slice(0, offset)]; console.log(offset([1, 2, 3, 4, 5], 2)); console.log(offset([1, 2, 3, 4, 5], -2));
