Linear Interpolation (Lerp) - Math and JavaScript Applications
Linear interpolation (Lerp) is a very important technique I use all the time. In this video I won’t just give you the formula, but teach you how to figure it out by yourself when needed. I think you’ll remember the math better in that way. Then, once the formula is clear, I’ll show you how to use it in JavaScript. I'll teach you several different applications where we animate location, color, sound and text!
I made this video because many of my students make the mistake of not extracting lerp as its own function when they use it multiple times in an application. Then, the code has countless different implementations all over the place. This kind of spaghetti code leads to a lot of bugs.
