Build Angular Appplication

Building Angular Applications

below steps are for creating angular Application

Downloading and installing Node.js and npm
Install Angular CLI
Create an app with Angular CLI
Build & Open the application

1. Downloading and installing Node.js and npm

Angular required node.js, we need to download NPM(Node Package Manager).
we can download it from here- https://nodejs.org/en/
Once you have installed Node.js, you can use the npm command to install TypeScript, open command prompt & type this below command-

 npm install npm –g

it will install all packages globally. g stand for global.
once you have done it. you can check which node version installed in your machine.

 node -v

2. Install Angular CLI

To install Angular CLI, run

$ npm install -g @angular/cli

This will install the ng command globally on your system. ng stands for Angular.
check angular CLI version with help below command

 ng v

3.Create an app with Angular CLI

now we can create an angular project with the help of below command

 ng new my-first-angular-app

once you run this above command it will ask for router configuration.
If you say “Yes” then CLI will automatically add router configuration to your project.
it will installed/include all related files inside project directory.

Angular App Structure

once you have created project these files will be included.

4.Build & Open the application

To build & open Application you need to run below command

 ng serve --open

once you run this command project will build & open in your local machine.

The server automatically rebuilds the app and reloads the page when you change any of the source files.

JavaScript type hoisting with variable function Expression

JavaScript type hoisting with variable function Expression Hoisting is JavaScript default behavior to moving declaration on the top. Variable can be used before its declaration. To understand this, first we need to understand of hoist meaning, hoist means “raise(something) by means of ropes & pulleys”. now we can relate hoisting with JavaScript. JavaScript interpreter moves all declaration on the top at runtime. It is best practice to declare all variable at the top of their respective scopes. , JavaScript is loosely syntax language so it will not throw any error at runtime if the variable used before its declaration. But JavaScript does not allow variable used before its declaration in “use strict” mode. Example 1 In this example, we can see in a normal scenario, when y has declared & then used. in this case, it will give output 10 as excepted. <p id= "demo" ></p> <script> var y; //Declare y y = 10 ; ...

JavaScript Closure

What is closure? It is my personal experience, I have never understood closure, I have read many articles & have seen many videos. Finally, I understood sometimes we even used a closure without realizing we were using a closure. First, understand the meaning of closure “an act or process of closing something”, now we can relate closure in javascript, closure is an inner function which wraps inside the outer function, which can access outer function scope & global function scope. for scoping you can read my previous blog:- http://uisource.blogspot.com/2018/08/javascript-variable-scoping.html why do we create? Global variables can be made local (private) with closures. To avoid the usage of global variables, use the local variables and wrap your code in the closure. A closure is an inner function that has access to the outer (enclosing) function’s variables—scope chain(Lexical scoping). The closure has three scope chains: it has access to its own scope (variables define...

JavaScript Variable Scoping

There are two types of variables in JavaScript. Global variables have global access and are declared outside of any function. Local variables are those declared inside of function. Lexical Scoping(Nested JavaScript Function) means that in a nested group of functions, the inner functions have access to the variables and other resources of their parent scope. Global variable:- Global variable declares & initialize outside the function, & accessible in from anywhere in the code. The global variable always stored in memory even function execution finish, it always keeps in memory or always accessible from anywhere in the code. Example 1 var message= "hello i am global variable" ; //global variable function a (){ console.log(message); // output: hello i am global variable } function b (){ console.log(message); // output: hello i am global variable } function a() function b() In above example message is a global variab...
