Underscore.JS - reject 方法

語法

_.reject(list, predicate, [context])

reject 方法 iterates over a given list of element, calls the predicate on each element. 返回所有不匹配的案例。

示例

var _ = require('underscore');

var list = [1, 2, 3, 4, 5, 6]
//Example 1. find even numbers using reject method
var result = _.reject(list, function(num) { return !(num % 2 == 0) });
console.log(result);

//Example 2. find odd numbers using reject method
var result = _.reject(list, function(num) { return (num % 2 == 0) });
console.log(result);
