Finding the height based on width and screen size ratio (width:height) in JavaScript
Problem
We are required to write a JavaScript function that takes in the width of the screen as the first argument and the aspect ratio (w:h) as the second argument. Based on these two inputs our function should return the height of the screen.
Example
Following is the code −
const ratio = '18:11'; const width = 2417; const findHeight = (ratio = '', width = 1) => { const [w, h] = ratio .split(':') .map(Number); const height = (width * h) / w; return Math.round(height); }; console.log(findHeight(ratio, width));
Output
Following is the console output −
