Javascript px to Rem function

remCalc.ts

/**
 * Converts pixel size to rem and accepts the base as second argument. default base is 16px
 *
 * @param {number|string} px
 * @param {number} base
 * @return {string}
 */
const remCalc = (px: number | string, base: number = 16) => {
  const tempPx = `${px}`.replace('px', '')

  return (1 / base) * parseInt(tempPx) + 'rem'
}

Simplified this a bit and made TS happy:

const remCalc = (px: number | string, base: number = 16) => {
  const tempPx = `${px}`.replace('px', '')

  return (1 / base) * parseInt(tempPx) + 'rem'
}

Great, sweet and simple, updated the code to this
