A real-world implementation of the last algorithm ‘008-letter-frequency’. Given an array of objects, create a new object that lists the frequency that the property ‘category’ occurs.

The challenge in this algorithm is when given a string, return the frequency of each letter in the string, in addition, ignore any spaces, special characters or numbers …

article

This algorithm verifies that the sum of two or more number follows the following rules, and outputs an object with the results…

article

This algorithm did not come from a challenge but instead from a project I was working on. I had an array of objects that had to be filtered with another array…

article

This algorithm introduces the notion of nested loops and comparisons.

Another simple string algorithm. In this one, the challenge is to return the provided string with the first letter of each word capitalized. Make sure the rest of the word is in lower case.
