JavaScriptmas is a 24-day long, daily coding challenge organized by the Norwegian online coding school, Scrimba, starting from December 1st until December 24th, 2020. It strictly consists of JavaScript exercises, as its name suggests.
In this repository I committed all my solutions to the exercises. My certificate of completion can be viewed on LinkedIn.
Scrimba's Advent Calendar containing all of the exercises can be found here.

You are given an array of integers representing coordinates of obstacles situated on a straight line. Assume that you are jumping from the point with coordinate 0 to the right. Ypu are allowed only to make jumps of the same length represented by some integer. Find the minimal length of the jump enough to avoid all the obstacles.

GoDaddy makes a lot of different top-level domains available to its customers. A top-level domain is one that goes directly after the last dot ('.') in the domain name, for example, .com in example.com. To help the users choose from available domains, GoDaddy is introducing a new feature that shows the type of the chosen top-level domain. You have to implement this feature. To begin with, you want to write a function that labels the domains as "commercial", "organization", "network", or "information" for .com, .org, .net or .info, respectively. For the given list of domains, return the list of their labels.

We are making a Social Media Character Counter! We want to display the available characters LEFT. Using the keydown() event should help you here. When the characters reach 20 and below, we want them to turn red. So we will use Javascript to add that styling to it. If the characters drop below 0, we want the button to be disabled BUT if there are only 0 characters left, we should still be able to tweet.
