Leetcode
Given an array points where points[i] = [xi, yi] represents a point on the X-Y plane, return true if these points are a boomerang.
A boomerang is a set of three points that are all distinct and not in a straight line.
Example 1:
Input: points = [[1,1],[2,3],[3,2]] Output: true
Example 2:
Input: points = [[1,1],[2,2],[3,3]] Output: false
Solution
var isBoomerang = function(points) {
const [x1, y1] = points[0];
const [x2, y2] = points[1];
const [x3, y3] = points[2];
return (x2 - x1) * (y3 - y1) !== (y2 - y1) * (x3 - x1);
};
