Kishn: 第四题：[code=javascript] function where(collection, source) { let arr = [].concat(collection); for (let key in source) { arr = arr.filter(item => item[key] === source[key]) } return arr; } [/code]

u013346321: 第四题应该是这样，[code=plain] function where(collection, source) { var arr = [].concat(collection); // What's in a name? var curr_key = ""; for (var key in source) { // console.log(key); //获取key值 // console.log(source[key]); //获取对应的value值 curr_key = key; arr = arr.filter(function (item) { console.log(curr_key) return item[curr_key] === source[curr_key]; }) } return arr; } [/code]

u013346321: 第四题不对吧， where([{ first: "Romeo", last: "Montague" }, { first: "Mercutio", last: null }, { first: "Tybalt", last: "Capulet" }], { first: 'Romeo', last: "Capulet" }) ， 这个应该没有返回值的，但是还是返回了 {first: "Tybalt", last: "Capulet"}
