Coding challenges are online platforms or exercises that test a programmer's skills by providing coding problems to solve, often with a competitive or timed element. These challenges help developers improve their coding abilities, prepare for technical interviews, and stay up-to-date with industry trends, making them a valuable resource for programmers of all levels, from beginners to experienced professionals.
Coding challenges are trending due to the recent launch of new platforms such as React Challenges and Everybody.codes, which offer alternative coding challenge experiences. The discussions are centered around improving the typical React challenge platform experience and the novelty of having a coding challenge event in November, similar to Advent of Code. The community is showing interest and enthusiasm for these new initiatives, driving the momentum behind the topic.
