Find the nearest value to the given one.

You are given an Array of numbers and a value for which you need to find the nearest one.

For example, we have the following sequence of numbers: 4, 7, 10, 11, 12, 17, and we need to find the nearest value to the number 9. If we sort this sequence in the ascending order, then to the left of number 9 will be number 7 and to the right - will be number 10. But 10 is closer than 7, which means that the correct answer is 10.

A few clarifications:

If 2 numbers are at the same distance, you need to choose the smallest one;
The sequence of numbers is always non-empty;
The given value can be in this sequence, which means that it’s the answer;
The sequence may contain both positive and negative numbers, but they are always integers;
The sequence isn’t sorted and consists only unique numbers.

Input: Two arguments: an Array of numbers and sought value as a number.

Output: A number.

Examples:

assert.strictEqual(nearestValue([4, 7, 10, 11, 12, 17], 9), 10);
assert.strictEqual(nearestValue([4, 7, 10, 11, 12, 17], 8), 7);
assert.strictEqual(nearestValue([4, 8, 10, 11, 12, 17], 9), 8);
assert.strictEqual(nearestValue([4, 9, 10, 11, 12, 17], 9), 9);
