 * Map a value from an input range to an output range.
 * @link https://www.remotion.dev/docs/interpolate
 * @param {!number} input value to interpolate
 * @param {!number[]} inputRange range of values that you expect the input to assume.
 * @param {!number[]} outputRange range of output values that you want the input to map to.
 * @param {?object} options
 * @param {?Function} options.easing easing function which allows you to customize the input, for example to apply a certain easing function. By default, the input is left unmodified, resulting in a pure linear interpolation {@link https://www.remotion.dev/docs/easing}
 * @param {string=} [options.extrapolateLeft="extend"] What should happen if the input value is outside left the input range, default: "extend" {@link https://www.remotion.dev/docs/interpolate#extrapolateleft}
 * @param {string=} [options.extrapolateRight="extend"] Same as extrapolateLeft, except for values outside right the input range {@link https://www.remotion.dev/docs/interpolate#extrapolateright}
