Centralized scaling algorithm for React Native

reactNativeScaler.js

const { width, height } = Dimensions.get('window');

const heightAspect = 568; 
const widthAspect= 320;

const verticalScale = height / heightAspect;
const horizontalScale = width / widthAspect;

export const scale = (size) => (verticalScale / horizontalScale) * size;
export const scalePx = (sizePx) => {
  const i = parseInt(sizePx, 10);
  return `${scale(i)}px`;
};
