    A Virtual Environment is a python environment, that is an isolated working copy of Python which allows you to work on a specific project without affecting other projects
    So basically it is a tool that enables multiple side-by-side installations of Python, one for each project.

    Creating virtual environment in Linux

    If pip is not in your system

    $ sudo apt-get install python-pip

    Then install virtualenv

    $ pip install virtualenv

    Now check your installation

    $ virtualenv --version

    Create a virtual environment now,

    $ virtualenv virtualenv_name

    After this command, a folder named virtualenv_name will be created. You can name anything to it. If you want to create a virtualenv for specific python version, type

    $ virtualenv -p /usr/bin/python3 virtualenv_name

    or

    $ virtualenv -p /usr/bin/python2.7 virtualenv_name

    Now at last we just need to activate it, using command

    $ source virtualenv_name/bin/activate

    Now you are in a Python virtual environment

    You can deactivate using

    $ deactivate

    Creating Python virtualenv in Windows

    If python is installed in your system, then pip comes in handy.
    So simple steps are:
    1) Install virtualenv using

     > pip install virtualenv

    2)Now in which ever directory you are, this line below will create a virtualenv there

     > virtualenv myenv

    And here also you can name it anything.

    3) Now if you are same directory then type,

     > myenv\Scripts\activate

    You can explicitly specify your path too.

    Similarly like Linux you can deactivate it like

    $ deactivate

    javascript – Script Tag – async & defer

    Async and Defer

    Normally HTML page execution starts line by line. When an external JavaScript <script> element is encountered, HTML parsing is stopped until a JavaScript is download and ready for execution. This normal page execution can be changed using the defer and async attribute.

    Defer

    When a defer attribute is used, JavaScript is downloaded parallelly with HTML parsing, but it will be execute only after full HTML parsing is done.

    <script src="/local-js-path/myScript.js" defer></script>
    

    Async

    When the async attribute is used, JavaScript is downloaded as soon as the script is encountered and after the download, it will be executed asynchronously (parallelly) along with HTML parsing.

    <script src="/local-js-path/myScript.js" async></script>

    How To Add JavaScript to HTML

    You can add JavaScript code in an HTML document by employing the dedicated HTML tag <script> that wraps around JavaScript code.

    The <script> tag can be placed in the <head> section of your HTML or in the <body> section, depending on when you want the JavaScript to load.

    Generally, JavaScript code can go inside of the document <head> section in order to keep them contained and out of the main content of your HTML document.

    <!DOCTYPE> – Definition and Usage

    The declaration must be the very first thing in your HTML document, before the tag.

    The declaration is not an HTML tag; it is an instruction to the web browser about what version of HTML the page is written in.

    In HTML 4.01, the declaration refers to a DTD, because HTML 4.01 was based on SGML. The DTD specifies the rules for the markup language, so that the browsers render the content correctly.

    HTML5 is not based on SGML, and therefore does not require a reference to a DTD.

    Tip: Always add the declaration to your HTML documents, so that the browser knows what type of document to expect.

    From : W3 schools HTML Declaration

    How can I validate an email address in JavaScript? Using regular expressions is probably the best way. You can see a bunch of tests here const validateEmail = (email) => { return String(email) .toLowerCase() .match( /^(([^<>()[\]\\.,;:\s@"]+(\.[^<>()[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9Read more

    How can I validate an email address in JavaScript?

    Using regular expressions is probably the best way. You can see a bunch of tests here

    const validateEmail = (email) => {
      return String(email)
        .toLowerCase()
        .match(
          /^(([^<>()[\]\\.,;:\s@"]+(\.[^<>()[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/
        );
    };

    Here’s the example of a regular expression that accepts unicode:

    const re =
      /^(([^<>()[\]\.,;:\s@"]+(\.[^<>()[\]\.,;:\s@"]+)*)|(".+"))@(([^<>()[\]\.,;:\s@"]+\.)+[^<>()[\]\.,;:\s@"]{2,})$/i;

    But keep in mind that one should not rely only upon JavaScript validation. JavaScript can easily be disabled. This should be validated on the server side as well.

    Here’s an example of the above in action:

    const validateEmail = (email) => {
      return email.match(
        /^(([^<>()[\]\\.,;:\s@"]+(\.[^<>()[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/
      );
    };
    const validate = () => {
      const $result = $('#result');
      const email = $('#email').val();
      $result.text('');
    
      if (validateEmail(email)) {
        $result.text(email + ' is valid :)');
        $result.css('color', 'green');
      } else {
        $result.text(email + ' is not valid :(');
        $result.css('color', 'red');
      }
      return false;
    }
    $('#email').on('input', validate);
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
    <label for="email">Enter an email address: </label>
    <input id="email" />
    <h2 id="result"></h2>
