使用 JavaScript 查找二维平面中两点之间的距离
问题
我们需要编写一个 JavaScript 函数,该函数接收两个对象,这两个对象都具有 x 和 y 属性,用于指定平面中的两个点。
我们的函数应该查找并返回这两个点之间的距离。
示例
以下为代码 -
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));
