parsegraph-lerp

This module provides a single function called lerp, which linearly interpolates between two endpoint values using a given interpolation value.

import lerp from 'parsegraph-lerp';

const start = 2;
const end = 4

// interp=0
assert.equal(lerp(start, end, 0), 2);

// interp=0.5
assert.equal(lerp(start, end, 0.5), 3);

// interp=1
assert.equal(lerp(start, end, 1), 4);
