In browsers, the top-level scope is the global scope. That means that in browsers if you're in the global scopevar somethingwill define a global variable. In Node this is different. The top-level scope is not the global scope;var somethinginside a Node module will be local to that modu...
letandconstdeclarations define variables that are scoped tothe running execution context’sLexicalEnvironment. The variables are created when their containingLexical Environmentis instantiated but may not be accessed in any way until the variable’sLexicalBindingis evaluated. A variable defined by aLexical...
一、定义多个 store 说明 我们在开发大型项目的时候会有很多的状态,比如说关于用户的,关于产品的,等等之类的,如果我们把他放在一个 store 里面就会变得非常难以维护 在原有的 note.js...store 上在加一个关于用户登录的 user.js import { ref } from 'vue' import { defineStore } from 'pinia' export cons...
-d, --define <expr>[=value] Global definitions. -e, --enclose [arg[:value]] Embed everything in a big function, with configurable argument(s) & value(s). --expression Parse a single expression, rather than a program (for parsing JSON). --ie Support non-standard Internet Explorer. ...
let bar = 'global' function test() {} console.dir(test) 在Chrome浏览器的控制台中,通过执行上述代码,查看 test 函数的作用域链,其结果如图: 由上图可知,let 在全局环境声明变量 bar 保存在[[Scopes]][0]: Script这个变量对象的属性中,而[[Scopes]][1]: Global就是我们常说的全局对象。

void 0→ undefined (if there is a variable named "undefined" in scope; we do it because the variable name will be mangled, typically reduced to a single character) Conditional compilation You can use the --define (-d) switch in order to declare global variables that UglifyJS will assume ...
