Maps a number's relative placement within one range to the equivalent position in another range. For example, given the range of 0 to 100, 50 would be halfway between so if it were mapped to a range of 0 to 500, it would be 250 (because that's halfway between that range). Think of it like ratios.

Map one range to another (ex: mapRange(-10, 10, 0, 100, 5)--> 75). normalize() Map a number within a range to a progress between 0 to 1 (ex: normalize(100, 200, 150) --> 0.5 ).
GSAP's utility methods can be surprisingly helpful. Note that many of them can optionally return FUNCTIONS so that they can be plugged directly into tweens, leveraging GSAP's function-based capabilities. In that case, they'll get called once for each target rather than just using the same end value for them all.
GSAP works around countless browser inconsistencies; your animations **just work**. At its core, GSAP is a high-speed property manipulator, updating values over time with extreme accuracy. It's up to 20x faster than jQuery! See https://greensock.com/why-gsap/ for what makes GSAP so special.

Sep 15, 2020 · I find it offers more possibilities and just works better for me. In today’s tutorial, we’ll be using four dials to change the hsla background color of an element. To do this, I used the handy mapRange () utility method and Draggable plugin from GreenSock. These are free tools available to anyone.
