如果想根据两个对象的属性是否相等,来判断对象是否相等,可以参考underscore:isEqual(obj1, obj2): // Internal recursive comparison function for `isEqual`. var eq, deepEq; eq = function(a, b, aStack, bStack) { // Identical objects are equal. `0 === -0`, but they aren't identical. //...
class TypedMap extends Map { constructor(keyType, valueType, entries) { // If entries are specified, check their types if (entries) { for(let [k, v] of entries) { if (typeof k !== keyType || typeof v !== valueType) { throw new TypeError(`Wrong type for entry [${k}, ${...
87. Check if Two Arrays Are Similar with One Swap Write a JavaScript program to determine if two arrays of integers of the same length are similar. The arrays will be similar if one array can be obtained from another array by swapping at most one pair of elements. ...
There are a lot of useful matchers that come with Jasmine. Later in this section, you’ll also see how to build your own. Equality: toEqual Perhaps the simplest matcher in Jasmine istoEqual. It simply checks if two things are equal (andnotnecessarily the same exact object, as you’ll ...
