Top 25 websites for Coding

Here are some Top 25 websites for Coding and competitions to learn the art of coding.

It’s the year 2020. It’s the final year of a decade and the beginning of a new. Through the past 10 years of humans flourishing in the midst of a flourish on Earth we’ve made incredible advances with respect to Science and Technology. A few examples such as The first time we landed on Mars using Curiosity Rover (2012), the first landing on Mars with Curiosity Rover (2012), the detection of gravitational waves in the depths of space (2015) as well as the introduction of a superpower for editing genes -CRISPR CRISPR (2018), “taking” the first-ever image of a black-hole using The Event Horizon Telescope (2019).

Similar to the previous point the most important breakthrough in the decade of 2010 is the development in the field of Artificial Intelligence or more commonly referred to as A.I. With AI technology, science fiction is brought to life. Machine Learning allows machines to learn, and Deep Learning — an effort to recreate the complexity of the human brain using artificial neural networks creating a mind that is their own. 

Technology continues to improve with its advances, Deep Learning pundits are always focusing on one end goal: to build the concept of an Artificial General Intelligence, which is a machine capable of carrying out any type of tasks, similar to human beings.

Each quantum leap that you have read about was made possible by computer programming. For instance, Curiosity Rover was one of them. Curiosity Rover was programmed ahead of time so that it could explore Mars independently without any human involvement, and generating the image of the black hole needed an algorithm that could collect images from a collection of satellites located on Earth’s surface. Earth. This method of communicating with computers was the basis for numerous scientific discoveries that we can see in the present. Without it our society will remain in a state of stagnation.

Anyone can code.

In this age of exponentially growing amounts of data, I feel that every person should learn the art of programming. CEOs, founders and executives, business owners, and VCs seniors and children. As the gap between the rich and the poor continues to grow and inequality persists the need for coding will become essential and necessary to survive.

The best part is that anyone is able to learn how to code! What’s the downside? Coding can be a challenge. However, if you have the right qualities: determination, curiosity, and the will to do it you will be able to do it. Programming is also about solving problems. It’s the basic idea of programming. It’s typically employed to automate an otherwise monotonous task.

Additionally one of the most effective methods to master code is through practicing, lots and lots of practice. It will help you make coding a routine. What better way to develop your skills while you are learning how to code, than by participating in code challenges and competitions?

Below are the 20 sites that I have compiled to help you learn to program and gives with the chance to tackle complex algorithmic issues.

The list isn’t ordered in any way. Therefore, scroll down and enjoy the list!
