If you want to know everything about Angular framework, start an Angular project or become an Angular developer , this guide is for you. We’ve put together a list of the best books, tutorials, and courses for learning Angular and improving your skills. You will also learn about the different types of Angular and their uses. Let’s go.

Angular is a free and open source framework used to build single page client applications with HTML and typescript. Angular is written in TypeScript. The framework implements the basic functionality in TypeScript libraries that you can import into your complex applications.

The basic Angular key blocks are components organized into modules. These modules collect the associated code into functional sets. A set of modules defines an Angular application. Most applications have a root module that supports a bootstrap component.

What is Angular for?

Angular is a framework typically used in building scalable web applications with a collection of libraries and built-in features such as client-server communication and routing. To understand how Angular can be useful, it helps to know some of its applications, which are listed below.

  • Web applications. Angular is used for web development. Since Angular 5, it has been used to develop modern web applications.
  • Desktop applications. Developers use Angular to create complex web applications installed on the desktop for Mac, Windows and Linux. Angular platforms are decent choices for developers working with line of business applications with high standards of code reliability.
  • Native mobile applications. Angular can be used to develop native mobile applications through NativeScript. Native mobile apps are generally fast and reliable compared to other apps.
  • Single Page Applications (SPA). Angular is also used to create single page client applications. SPAs are web applications that load a single HTML page and the page updates dynamically based on user interaction with the web application. SPAs can use back-end servers without necessarily referencing the entire web page to download data.

Angular types

There are over 12 versions of Angular released over the years. The very first version, Angular JS, had some differences and limitations which have been fixed in newer versions. Below are the types of Angular that exist today.


Angular 1, commonly known as AngularJS , uses JavaScript to build the app and is based on a model view controller or MVC design. AngularJS does not offer built-in support for application development, but does support native mobile applications. AngularJS will continue to be supported long term until the end of 2021.

Angular 2 through 11

Angular 2 is a redesign of the original AngularJS. This version and subsequent versions released over the years have offered better scalability and improvements based on lessons learned from AngularJS. All of these versions have included improvements, but are based on the same framework.

Angular 12

Angular 12 is the last version of this TypeScript available on a web based framework. It was released in May 2021. This version favors Ivy, which is a compilation and rendering pipeline technology that offers faster AOT compilation.

How long does it take to learn Angular ?

The answer will vary depending on your level of engagement, but in general you need to spend at least two or three hours a day for two or three months. During this time, you will learn to understand its basics, including Angular components, directives, data binding, routing, and dependency injection.

How to learn Angular: a step by step guide

There are a few basic steps you need to follow to learn Angular. They will help you understand the basics. From there, you can then learn the more advanced aspects of the Angular framework.

  1. Install all Angular prerequisites. Before you start with Angular, you will need to install a few prerequisites and become familiar with them. These include Typescript, Node, and VS Code.
  2. Configure an Angular development environment. Once you have the basics, you can move on to setting up your local development environment. This is what you will use to develop Angular apps. You can use your computer as a local development environment to start learning the basics.
  3. Create a sample Angular application project. Now that you have Angular and its dependencies installed, you can move on to create an Angular sample app project to help you understand the basics. There are a variety of tutorials online that you can use to walk you through some simple projects.
  4. Study the concepts of Angular architecture. Once you’ve set up a sample project, you can start digging deeper into the different concepts you’ll be using on a regular basis on your Angular journey. These include modules, components, models, metadata, data bindings, directives, services, and dependency injection.
  5. Find out how to update Angular applications to the latest version of Angular. Angular is constantly improving and releasing new versions. Learning how to keep your Angular applications up to date will allow you to take advantage of the latest features and optimizations.

    How can I make a time delay in Python?

    5 answers

    I would like to know how to put a time delay in a Python script.


    Answer #1

    import time
    time.sleep(5)   # Delays for 5 seconds. You can also use a float value.

    Here is another example where something is run approximately once a minute:

    import time
    while True:
        print("This prints once a minute.")
        time.sleep(60) # Delay for 1 minute (60 seconds).


    Answer #2

    You can use the sleep() function in the time module. It can take a float argument for sub-second resolution.

    from time import sleep
    sleep(0.1) # Time in seconds
