javascript - Lodash - 从两个数组返回非共享元素的方法

Question

Helo 伙计们，你能帮忙:

我需要一个返回 lodash 的方法:

_.method( [1,2,3,4,5,6,7], [1,2,3] ) => [4,5,6,7]

换句话说，返回非共享元素的方法。

最好的问候格雷格。

Answer 1

你可以使用 _.difference .

Creates an array of array values not included in the other given arrays using SameValueZero for equality comparisons. The order and references of result values are determined by the first array.

var result = _.difference([1, 2, 3, 4, 5, 6, 7], [1, 2, 3]);
console.log(result);
