How does JavaScipt work?
A client-side script is a programming language that performs its tasks entirely on the client’s machine and does not need to interact with the server to function. For instance, if you have a Web page loaded on your computer and your Internet service provider goes down, you are still able to interact with the Web pages already loaded on your browser. You will not, however, be able to navigate to new Web pages or access any data located remotely.
- Loading new content or data onto the page without reloading the page
- Rollover effects and dropdown menus
- Animating page elements such as fading, resizing or relocating
- Playing audio and video
- Validating input from Web forms
- Repairing browser compatibility issues
Take a search engine for example. Today, search engines almost all have an autocomplete function. The user begins typing a word into the search box and a list of possible search terms or phrases appears below. The experience is seamless. Suggested search terms appear without reloading the page.
Only once the user selects a search term does the entire page reload and produce the search results. Engines such as Google have reduced or eliminated the need to reload, even for that step. They simply produce results using the same asynchronous process.

The paid resources are also very cheap, and you can purchase on just $9.99 during their flash sale, which happens quite often. It’s full of some of the great teachers like Colt_Steele, Rob Percival, Stephen Grider, Jose Marcial Portilla, John Purcell, etc.
This is one of the most awesome community websites which will help you to learn to code for free, build real-world projects, and get a job as a developer.
Founded by Quincy Larson, this is a really excellent place to start your coding journey. They even have a big Facebook group (freecodecampearth) where you can ask questions and share your learning experience, and their Medium publication freeCodeCamp is the most significant Medium publication for Programming articles.
As Quincy Larson pointed out in comments, freeCodeCamp also has a YouTube channel, which has hundreds of free courses on topics like Python, Git, GraphQL, SQL, database schema design, and a lot of advanced topics. Many of these are 10+ hours long — in a single video with no ads. Perfect to start your journey.
The best part of Coursera is that it offers online courses from Universities like Stanford, University of London, University of Michigan, Colorado, Imperial College of London, and many more.
Coursera also provides you Certification, which you can showcase in your Linkedin profile, but you need to pay for it.
And, if you find Coursera courses useful, which they are because they are created by reputed companies like Google, IBM, Amazon, and best universities around the world, I suggest you join the Coursera Plus, a subscription plan from Coursera
This single subscription gives you unlimited access to their most popular courses, specialization, professional certificate, and guided projects. It cost around $399/year but its complete worth of your money as you get unlimited certificates.

One of the best websites to learn any technology, skills like Web Development, Mobile Development, and Programming language like Java, Web development framework like Angular, React, Spring Framework, Hibernate, etc.
It’s also now acquired CodeSchool, which earlier allows you to learn web technologies by doing it. I use this website to learn a lot of cool stuff in no time.
By the way, you would need a Pluralsight membership to join this course which costs around $29 per month and $299 per annum (14% discount) but its completely worth it. Alternative. you can also use their 10-day-free-trial to watch this course FREE.
Mozilla is a serious learner, a programmer who loves to do their own thing and just wants to read the theory and try examples in their own setup.
