For instance, case matters. A capital letter "A" is not equal to the lowercase "a". Which one is greater? The lowercase "a". Why? Because the lowercase character has a greater index in the internal encoding table JavaScript uses (Unicode). We'll get back to specific details and consequences of this in the chapter Strings.
比如说,字符串比较对字母大小写是敏感的。大写的 "A" 并不等于小写的 "a"。哪一个更大呢?实际上小写的 "a" 更大。这是因为在 JavaScript 使用的内部编码表中(Unicode),小写字母的字符索引值更大。我们会在 字符串 这章讨论更多关于字符串的细节。
There exist many "system" symbols that JavaScript uses internally, and we can use them to fine-tune various aspects of our objects.
JavaScript 内部有很多"系统" Symbol,我们可以使用它们来微调对象的各个方面。
