JavaScript保留字和对象 [英] Javascript reserved word and object

问题描述

我正在制作单词词典，所以有1,000,000+个单词. 当我需要存储单词constructor时，问题就来了.我知道这是javascript中的保留字，但我需要将其添加到字典中.

I'm making a dictionary of words, so there are 1,000,000+ words. The problem comes when I need to store the word constructor. I know this is a reserved word in javascript, but I need to add it to the dictionary.

var dictionary = {} 
console.log(dictionary ['word_1']) 
//undefined, this is good
console.log(dictionary ['word_2']) 
//undefined, this is good
console.log(dictionary ['constructor']) 
//[Function: Object] 
// this cause initialization code to break

我该如何解决?我可以像key=key+"_"那样弄糟它，但这似乎很糟糕.我还能做些什么吗?

How can I fix this? I could muck with the it like key=key+"_" but that seems bad. Is there anything else I can do?

推荐答案

您可以使用内置的Map类型而不使用JS对象，该类型将字符串/符号用作键，并且不与任何现有属性冲突

Instead of using a JS object, you could use the built-in Map type which uses strings/symbols as keys and does not conflict with any existing properties.

替换 var dictionary = {}与var dictionary = new Map()
