Controlling the Frame Rate with requestAnimationFrame

Limiting the frame rate while using requestAnimationFrame can be a common want especially when coding Games where you want your animations and mechanics to not exceed a particular mark of frames per second. Let’s go through 2 ways of doing it.

Quick and Easy Way

export function getGrid (size) {
  const length = Math.pow(size, 2)
  const offset = (size / 2) * -1

  const grid = Array.from({ length }).map((_, index, array) => {
    const row = Math.floor(index / size)
    const column = index % size

    const x = row + offset + 0.5
    const y = column + offset + 0.5
