JavaScript Variable Fundamentals
Welcome to the JavaScript documentation! This lab will give you an introduction to variables.
JavaScript
Uppercase Object Keys
In this lab, we will explore how to convert all the keys of an object to uppercase in JavaScript. You will learn how to use Object.keys() and Array.prototype.reduce() to create a new object with all the keys converted to uppercase letters. This technique can be useful in various scenarios where you need to standardize the keys of an object for consistency and ease of use.
JavaScript
Integer to Roman Numeral Conversion
In this lab, we will be exploring how to convert an integer to its roman numeral representation using JavaScript. We will use a lookup table to map the integer values to their corresponding roman numerals, and then use the reduce method to iterate over the values and build the roman numeral representation of the input integer. By the end of this lab, you will have a deeper understanding of how to manipulate arrays and strings in JavaScript to perform complex tasks.
JavaScript
Week of Year
In this lab, we will explore how to calculate the zero-indexed week of the year that a given date corresponds to using JavaScript.
