The javascript division operator also performs the usual arithmetic conversion. However, since JavaScript is loosely typed, this javascript operator does not act exactly as in C, Perl, and other strictly typed programming languages. In those languages, integer division is different from floating-point ...

函数是 JavaScript 中的基本组件之一。JavaScript 中的函数类似于过程——一组执行任务或计算值的语句。但要成为函数,这个过程应该接受输入并返回与输入存在某些明显关系的输出。要使用一个函数,你必须将其定义在你希望调用它的作用域内。 参见JavaScript 函数的详细参考章节,以了解详情。

闭包是由捆绑起来(封闭的)的函数和函数周围状态(词法环境)的引用组合而成。换言之,闭包让函数能访问它的外部作用域。在 JavaScript 中,闭包会随着函数的创建而同时创建。 词法作用域 注意下面的示例代码: jsCopy to Clipboard function init() { var name = "Mozilla"; // name 是 init 创建的局部变量 functi...
