Therefore, those blocks will share the same scope as the function which contains them. This way, it might be dangerous to declare vars inside blocks as it would seem the var belongs to that block only. Hoisting: On runtime, all var and function declarations are moved to the beginning of each function its scope - this is known as Hoisting.

Having said so, it is a good practice to declare all the vars altogether on the first line, in order to avoid false expectations with a var that got declared late but happened to hold a value before - this is a common problem for programmers coming from languages with block scope.

Source: JavaScript Scoping and Hoisting Function Binding Function binding is most probably the least of your concerns when beginning with JavaScript, but when you realize that you need a solution to the problem of how to keep the context of this within another function, then you might realize that what you actually need is Function.

In other words, the function defined in the closure 'remembers' the environment in which it was created in. It is an important concept to understand as it can be useful during development, like emulating private methods.

It can also help to learn how to avoid common mistakes, like creating closures in loops. Strict mode isn't just a subset: it intentionally has different semantics from normal code.

Browsers not supporting strict mode will run strict mode code with different behavior from browsers that do, so don't rely on strict mode without feature-testing for support for the relevant aspects of strict mode. Strict mode code and non-strict mode code can coexist, so scripts can opt into strict mode incrementally. Immediately-invoked function expressions can be used to avoid variable hoisting from within blocks, protect against polluting the global environment and simultaneously allow public access to methods while retaining privacy for variables defined within the function.

What is JavaScript ?

This pattern has been referred to as a self-executing anonymous function, but cowboy Ben Alman introduced the term IIFE as a more semantically accurate term for the pattern.Singletons differ from static classes or objects as we can delay their initialization, generally because they require some information that may not be available during initialization time.

Last updated by: That's what you should be looking for in a book.

Further motivation behind using the Observer pattern is where we need to maintain consistency between related objects without making classes tightly coupled. Instance WebAssembly. Here are all the features of client-side JavaScript, in living code.
