JavaScript_ 原始类型(primitive type) ECMAScript有5种原始类型,即:Undefined、Null、Boolean、Number和String。 typeof运算符 typeof运算符有一个参数,即要检查的变量或值。如: varsTemp = "our world!"; console.log(typeofsTemp);//输出"string"console.log(typeof2);//输出"number"...
In the first part of the series, Kirill Myshkin covers some aspects of JavaScript that help bring objects closer to primitive values, which allow benefiting from common language features that aren’t usually associated with an object, like comparisons an
JavaScript中,string、number、boolean均为primitive基本类型,也即字符串、数值、布尔值并不是以对象的形式而存在的。不过,由于需要对这三种primitive类型值进行操作,因此JavaScript会自动封装这三种类型的值,使其作为对象而拥有属性与方法。以string为例,这种封装过程如下: ...
What is the main difference between primitive types and objects in JavaScript?First, let’s define what are primitive types.Primitive types in JavaScript arestrings numbers (Number and BigInt) booleans (true or false) undefined Symbol values...
