 7th Day                                                                           

 Hey Guys, I hope that you have also installed Vs Code in your system. If you have not installed yet then please install it through 6.1 lecture. (Click this link  to go 6.1 lecture)Because from today we will work with Vs Code. 

                                      

                       So let's start with Vs Code.

        1.Click on file and select Open File/Open Folder and open it.

                                                                2.After open the folder/file make a html file name like index.html.

                         Right click on Vs-explorer and click on New file and give name.html

•  After creating html file .It will look like.....

                                      

• Type "doc+ Tab " in Vs Code it gives ready made code like..                                                                                                                                                                                                                             

                            

            So Friends we have learned each and everything which has mentioned above.

            Now we are going to do JavaScript Code and this code we can not use 

            outside the JS browser . For Example:

                                      Input:

                                      Output:

           Suppose, 

                 If this Same concept wants to execute on Command Prompt then it 

                 will be require JS Compiler which is called Node JS. 

                 Node JS is a JavaScript Runtime built on Chrome's V8 JavaScript 

                 engine. So Let's Install Node JS....

                                                      NODE JS

• It is a one type of JS Compiler.

                                        Importance of Node JS

•  We can use it on multiple operating system. 

• To make effective to JS, Node play vital role. 

• Using Node JS we can execute it out of our browser.                                          

                               1. Click here, Download Node JS.

                                   2. Select Version as your choice.

                                   3. And then install it.

                                   4. Check Node JS installed or not using cmd like:                                                           
                                       Just type: node -v , v12.18.3 has been installed.

                            So friends ,Now with the help of this Node JS ,We can run 

                            outside our browser. For Example: 

• Now Create file name.js and write code like: 
• And run through command prompt.
• Input:

                   

•  Output: Command is:  node hello.js
                                                                                                                                                                                                                  
• NODE PACKAGE MANAGER:  A package in Node.js contains all the files you need for a module. The NPM program is installed on your computer when you install Node.js .
• Using this command on cmd we can install: npm install jquery.
• After that it will install successfully NPM.
