which means that it’s easy - too easy - to reference the function before it is defined in the file. This harms readability and maintainability. If you find that a function’s definition is large or complex eno

To ensure the safest usage of this function, it's recommended to directly freeze the object without saving any reference to it in a variable.[!NOTE] Any object which was frozen before passing to freeze or deepFreeze will be returned as is and will not be proxied either. Hence they will ...
function (the pointer was passed by value when the function was called), this isn't helpful, as nobody outside the function will be affected by whether you change the pointer or not anyway. Placing the const after a reference is entirely useless and should be avoided. References cannot be ...
更准确一些的说法是,block statement阻止function declaration 被hoisted(变量提升)到作用域的顶部。这种定义方式与函数表达式类似。函数表达式的变量提升规则是下面这样: foo('before'); // Uncaught TypeError: foo is not a function var foo = function(location) { console.log('foo is called' + location); ...
A new Function A new RegExp Constant Objects and Arrays The keywordconstis a little misleading. It does not define a constant value. It defines a constant reference to a value. Because of this you can NOT: Reassign a constant value

To do this, one declares a constant as if it was a variable but add ‘const’ before it. One has to initialise it immediately in the constructor because, of course, one cannot set the value later as that would be altering it. For example, ...
【实例】ECMAScript规范说明中写到作为HoistableDeclaration的四种function声明:function,function*,async function和async function* Being able to reference a variable in its scope before the line it is declared, without throwing aReferenceError, but the value is alwaysundefined. ("Declaration hoisting") ...
