JS比较数组与自身除了相同的对象

Question

如何将数组与自身进行比较，而不是对同一对象进行比较

var i = 0;
var boo = true;
while (i < this.bombs.length) {
    if (this.bombs[i] === this.bombs[i]) {
        console.log("true");
        boo = true;
    } else {
        boo = false;
    }
    i++;
    return boo;
}

但不应使用bombs[i]

检查bombs[i]

您需要两个嵌套循环，并在指向同一个对象时跳过。这是一个天真的实现

let bombs = [{x: 1, y:2}, {x: 1, y: 4}, {x: 1, y: 2}];
let boo = false;

for (let i = 0; i < bombs.length && !boo; i++) {
    for (let j = 0; j < bombs.length; j++) {
        if (i === j) continue; // this is where you don't compare the object with itself
        if (bombs[i].x === bombs[j].x && bombs[i].y === bombs[j].y) {
            boo = true;
            break;
        }
    }
}
