Easing

Easing functions specify the rate of change over time and are useful when working with Svelte's built-in transitions and animations as well as the tweened and spring utilities. svelte/easing contains 31 named exports, a linear ease and 3 variants of 10 different easing functions: in, out and inOut.

You can explore the various eases using the ease visualiser in the examples section.
