How to Make Java Script Useful – Tips For Node.js Programmers
Many programmers and developers use this framework as it is open source and absolutely free.
Therefore, let us get to know the 10 most important concepts you must master as a developer.
Immediately-Invoked Function Expressions
We can describe an immediately invoked function expression (IIFE) as a self-invoking anonymous function. For limiting the scope of a variable or to avoid some name collisions, we can easily use this function.
You can also attach some important member functions to its objects by using this property as this is not IEnumerable. The best part is it has inheritance properties too.
The Module Pattern
Module pattern is same as Revealing Module pattern. So, we can create different variables and methods by using both the patterns.
Declaration of functions and variables can be placed anywhere. There is no fixed rule of positioning.
Hoisting is mainly important for variable assignment, function declaration, and variable declarations.
Apply, Call And Bind Methods
The call is the easiest method because users can invoke a function and also specify the context by using this method.
By using the apply method, we can pass arguments as an array but not separately.
Programmers can easily pass arguments to a function without invoking it by using the bind method.
This is basically an optimization technique. By using Memoization technique, we can execute some strong results.
When the same set of input occurring in a loop, it can return some interesting results by using this technique
We can use multiple methods for getting the same name but some different arguments. Method overloading technique is very important in this regard.
So, make sure you master these 10 amazing techniques to code better in JS.
