for the problem https://leetcode.com/problems/binary-search/submissions/

my code is:

var search = function(nums, target) {
	const tailRecursion = (start, nums, target) => {
		let len = nums.length;

		if (len == 0)
			return -1;

		let mid = ~~(len / 2);

		if (nums[mid] == target)
			return start + mid;

		if (nums[mid] < target)
			return tailRecursion(mid + 1, nums.slice(mid + 1, len), target);

		return tailRecursion(start, nums.slice(0, mid), target);
	}

	return tailRecursion(0, nums, target);
};

it works fine if i run the code in chrome devtool, but leetcode gives me runtime error. Please help.
