favoritos/src/helpers/get-context-gradient-entries.ts

Favoritos is a JavaScript plugin that adds some HTML5 canvas magic to your favicon. With just a wee bit of code, we can make some really cool effects.

export const getContextGradientEntries = (backgrounds: string[]): [number, string][] => {
  const arrayLength = backgrounds.length;
  const step = 1 / (arrayLength - 1);

  return backgrounds.map((background, index) => {
    return [index * step, background];
  });
};
