# Finding distance between two points in a 2-D plane using JavaScript

JavascriptWeb DevelopmentFront End Technology

## Problem

We are required to write a JavaScript function that takes in two objects both having x and y property specifying two points in a plane.

Our function should find and return the distance between those two points.

## Example

Following is the code −

Live Demo

const a = {x: 5, y: -4};
const b = {x: 8, y: 12};
const distanceBetweenPoints = (a = {}, b = {}) => {
let distance = 0;
let x1 = a.x,
x2 = b.x,
y1 = a.y,
y2 = b.y;
distance = Math.sqrt((x2 - x1) * 2 + (y2 - y1) * 2);
return distance;
};
console.log(distanceBetweenPoints(a, b));
