🏁MISSION

Cut Into Squares by freeman_lex -

You are given a rectangle, which is defined by its width w and height h, both positive integers. We allow a rectangle to be cut into two smaller rectangles with either a straight horizontal or a straight vertical cut at any integer position. The resulting smaller pieces can then be further cut into smaller pieces, as long as the length of the side being cut is at least two to allow a cut. Your task is to keep cutting the given rectangle into smaller pieces until each piece is a square, that is, the width of each piece equals its own height. This is always possible, since you could just keep cutting until the size of each piece has become 1-by-1. However, this function should return the smallest number of cuts that makes each piece a square.

assert.strictEqual(cutIntoSquares(4, 4), 0);
assert.strictEqual(cutIntoSquares(4, 2), 1);
assert.strictEqual(cutIntoSquares(7, 6), 4);

A Complete Guide to Beginning with JavaScript -

This guide is not itself the means to learn JavaScript. This guide addresses issues around getting started (obstacles, preliminary knowledge, etc.) and then points you to curated resources to start learning. Consider this material a prologue or an introduction to the learning process itself so, you have the needed background and context before beginning the learning process.

Generating Unique Random Numbers In JavaScript Using Sets -

Want to create more randomized effects in your JavaScript code? The Math.random() method alone, with its limitations, won’t cut it for generating unique random numbers. Amejimaobari Ollornwi explains how to generate a series of unique random numbers using the Set object, how to use these random numbers as indexes for arrays, and explores some practical applications of randomization.

The History And Future Of Regular Expressions -

Although JavaScript regexes used to be underpowered compared to other modern flavors, numerous improvements in recent years mean that’s no longer true. Steven Levithan evaluates the history and present state of regular expressions in JavaScript with tips to make your regexes more readable, maintainable, and resilient.

👩‍💻CODE SHOT

It's a very simple task! Dont be shy) How do you think, what the following code does?

function ????????(text: string): string {
    return text
        .split(/\b/)
        .map(x => [...x]
            .reverse()
            .join('')
        ).join('');
}
