问题 I have a multi-dimensional object: var obj = { prop: { myVal: "blah", otherVal: { // lots of other properties }, }, }; How would one traverse the entire object, without knowing any of the property names or the number of "dimensions" in the object? There are a couple other questions on SO that are related to the topic: Traverse through Javascript object properties javascript traversing through an object The problem is that both answers are not quite what I am looking for, because: a) The first

Comparing two arrays of objects for duplicate objects and push it when it's not a duplicate in JavaScript

由 大城市里の小女人 提交于 2019-12-12 01:38:09
问题 This question might be too similar to this question I asked a few hours ago, but the issue I was struggling with is actually more complex than I initially thought. I was not aware of the fact that no two objects can be considered to be same in JavaScript even when the two objects have the same set of properties and values. I have two arrays of objects like this in JavaScript. var from = [ {city: "seoul", country: "korea"}, {city: "tokyo", country: "japan"}, {city: "beijing", country: "china"}

Using namespacing with object literal notation and inheritance

由 荒凉一梦 提交于 2019-12-11 18:55:45

I am not able to initiate Scene object properly. console.log(scen1 instanceof xxx.prototypes.Scene); // false Basically Scene object should have all properties and methods from Scene + from Snippet and the result should be: console.log(scen1 instanceof xxx.prototypes.Scene); // true Any idea what I am doing wrong here? ; (function(xxx, window) { xxx

can I make Set/Map slap me when I try to use the wrong api on them?

由 拜拜、爱过 提交于 2019-12-11 17:45:21
问题 When I use Set and Map objects in javascript, I chronically say the wrong thing: set.length when I mean set.size map.length when I mean map.size map.someKeyName or map['someKeyName'] when I mean map.get('someKeyName') map.someKeyName=someValue or map['someKeyName']=someValue when I mean map.set('someKeyName', someValue) The result is a passive-aggressive undefined or silently failing to do what I wanted, which wastes my time. How hard would it be to make some kind of slightly-altered version
