Suitable For

This book is ideal for those seeking a deep theoretical understanding of algorithms. It is particularly beneficial for computer science students and professionals preparing for technical interviews or academic research.

Practical Code Example

While the book uses pseudocode, here’s a JavaScript implementation of the Merge Sort algorithm, inspired by the concepts covered:

function mergeSort(arr) {
    if (arr.length <= 1) {
        return arr;
    }

    const middle = Math.floor(arr.length / 2);
    const left = arr.slice(0, middle);
    const right = arr.slice(middle);

    return merge(mergeSort(left), mergeSort(right));
}

function merge(left, right) {
    let resultArray = [], leftIndex = 0, rightIndex = 0;

    while (leftIndex < left.length && rightIndex < right.length) {
        if (left[leftIndex] < right[rightIndex]) {
            resultArray.push(left[leftIndex]);
            leftIndex++;
        } else {
            resultArray.push(right[rightIndex]);
            rightIndex++;
        }
    }

    return resultArray
            .concat(left.slice(leftIndex))
            .concat(right.slice(rightIndex));
}

const array = [34, 7, 23, 32, 5, 62];
console.log(mergeSort(array)); // Output: [5, 7, 23, 32, 34, 62]

“JavaScript: The Good Parts” by Douglas Crockford

Suitable For

This book is perfect for intermediate to advanced JavaScript developers who want to refine their understanding of the language and adopt best practices.

Practical Code Example

Here’s a simple example illustrating the use of closures, one of the “good parts” of JavaScript:

function makeCounter() {
    let count = 0;
    return function() {
        count += 1;
        return count;
    };
}

const counter = makeCounter();
console.log(counter()); // Output: 1
console.log(counter()); // Output: 2
