ReferenceError: Cannot access 'a' before initialization let声明的变量不会提升,并且会产生暂存死区。在let声明变量之前访问变量会抛出错误。 第 3 题 var a = {n: 1} var b = a a.x = a = {n: 2} console.log(a.n, b.n); console.log(a.x, b.x); ...
// 第一个特性 --- 一旦声明不可修改consta=1;a=2;// Uncaught TypeError: Assignment to constant variable.// 第二个特性 --- 存在暂时性死区console.log(a);// Uncaught ReferenceError: Cannot access 'a' beforeinitialization(初始化前无法访问a)consta=1; ...
console.log(Person); // ReferenceError: Cannot access 'Person' before initialization class Person{ } console.log(Person) // [class Person] 2、函数受函数作用域限制,类受块作用域限制。 { class Person{ } } console.log(Person) // Person is not defined; ...
console.log(a) // Uncaught ReferenceError: Cannot access 'a' before initialization let a = 1 在'暂时性死区'的概念中，let和const声明的变量/常量都规避了变量提升(hoisting)特性带来的怪异逻辑，让前端程序员在编写代码时，以更严谨的角度去进行编程，防止多余的误操作。3.块级作用域 在ES6之前，只有全局...
开发者常戏称"函数是JavaScript中的一等公民",这足以体现了函数的重要性,为了更好的掌握函数我们需要学习函数的构造器Function等相关内容。 因为JavaScript的作用域与我们学习过的静态语言(如Java、C#等)有非常大的区别,理解作用域对更加深入的掌握JavaScript是非常有帮助的。
