 * Linear interpolation between two values controlled by a given fraction.
 * Note: no clamping is done to the fraction value.
 * @param {number} a

 * @param {number} fraction value between 0 and 1
 * @return {number}

 * @example
 *    lerp(1, 2, 0.5) === 1.5
 *    lerp(1, 2, 0) === 1
 *    lerp(1, 2, 1) === 2
