introduction about javascript

 

  •  the Javascript  is the most popular programming Language in the world , especially in building and development the websites .
  •  95%  of the websites are used javascript in it's structure , big companies like Facebook , Google , Amazon , Paypal and  Netflix used javascript to build it's own applications .
  •  As we know we use HTML to build the website structure , CSS for the presentation and javascript to make the website Dynamic because javascript makes the design interactive . where the user can interact with the wbsite . by javascript we can make animation for the images on our web page and also a part of the page can be updated by javascript . all that depends on a certain action the user will take on our web page.

 

 "JavaScript is a scripting language you can use to make web pages interactive ."

 

 

 Javascript is used in:

  1. Web Development in  Client side , and also in Server side by using Node.js Environment .
  2. Mobile Applications by using React Native .
  3.  IOT apps Developing  by using javascript IOT frameworks or javascript IOT platforms like IOT.js , Cylon.js .
  4. Game Development by using HTML Game Engine like phaser.js .

 

 

     JavaScript famous library such as :

  • jQuery .

  • Dojo toolkit .

     

    to be a good javascript developer , you should start to learn javascript basic principles which called (Native javascript ) or ( vanilla javascript ) .



    What is meant by vanilla JavaScript?
     
     
  • Vanilla JavaScript refers to using plain Javascript without any additional libraries or frameworks. The term became popular when Eric Wastl created the Vanilla JS site in 2012 as a joke. The site tries to bring attention to the fact that you can use just plain Javascript in many cases.
     
  • Learning “vanilla” JavaScript means learning the fundamentals of JavaScript. Frameworks and libraries help abstract and simplify some features of JavaScript which makes writing code faster and easier. But in the long run, it is important to know the fundamentals of JS to be able to learn the use of new frameworks faster and decide if a framework is needed at all.

Variable Scope in javascript

Image
      Scope determines the accessibility (visibility) of variables. JavaScript has 3 types of scope: Block scope Function scope Global scope   1. Block Scope : Before ES6 (2015), JavaScript had only Global Scope and Function Scope . ES6 introduced two important new JavaScript keywords: let and const . These two keywords provide Block Scope in JavaScript.  --------------------------------------------------------------------------------------------- Variables declared inside a { } block cannot be accessed from outside the block: Example: {    let x = 2 ; } // x can NOT be used here    ---------------------------------------------------------------------------------------------- Variables declared with the var keyword can NOT have block scope. Variables declared inside a { } block can be accessed from outside the block.  Example: {    var x = 2 ; } // x CAN be used here       note...

Shadowing

Image
  What is shadowing in javascript ?   Shadowing: Now, when a variable is declared in a certain scope having the same name defined on its outer scope and when we call the variable from the inner scope, the value assigned to the variable in the inner scope is the value that will be stored in the variable in the memory space. This is known as Shadowing or Variable Shadowing .       What is illegal shadowing ? Illegal Shadowing: Now, while shadowing a variable, it should not cross the boundary of the scope, i.e. we can shadow var variable by let variable but cannot do the opposite. So, if we try to shadow let variable by var variable, it is known as Illegal Shadowing and it will give the error as “variable is already defined.”

Hoisting

Image
            Hoisting   JavaScript hoists function declarations and variable declarations to the top of the current scope. Variable assignments are not hoisted ( JavaScript only hoists declarations, not initializations!). Declare functions and variables at the top of your scripts, so the syntax and behavior are consistent with each other.
