Get Premium | | New puzzle to train your brain and test your coding understanding✨ | | | Featured content | | Exclusive freelance networks are an incredible way to gain consistent access to dozens of new lucrative clients. | But there's a catch — they're exclusive — it's tough to get in. | It's definitely worth it, but you'll need to go through a grilling multi-stage process to be accepted into most of them. | Now coding quizzes are a core stage, and algorithm knowledge is crucial for you to go through. | Check these out and find out which areas you need to work on to maximize your chances of gaining entry. | The coding questions are an awesome way to test your algorithmic skills. | 1. Classic iteration | Standard stuff. | How to implement complex logic and output with while, do..while and for loops. | Common questions | How to: | Create shapes and structures with asterisks — like a right-angle triangle, or a pizza slice. Print Fibonacci numbers until n Print sum of numbers until n
| function printFibonacci(n) { let a = 0, b = 1, temp; for (let i = 0; i < n; i++) { console.log(a); temp = a + b; a = b; b = temp; } } printFibonacci(10);
| 2. Arrays | Lists are everywhere in life and code. | If you want to have any chance at the algorithms you'll meet, you need to know the in's and out's of inspecting and manipulating them. | Iteration, calculating sums, finding elements. | Common questions | Find the maximum value in an array. Calculate the sum of all elements. Rotate an array. Find the second largest element. Merge two sorted arrays.
| function rotateArray(arr, k) { const n = arr.length; k = k % n; // in case k is greater than array length return arr.slice(-k).concat(arr.slice(0, n - k)); } // Example let arr = [1, 2, 3, 4, 5]; let k = 2; let rotatedArr = rotateArray(arr, k); console.log(rotatedArr); // Output: [4, 5, 1, 2, 3]
| | | There's so much more to arrays than map(), filter(), find(), and push() . | But most devs are completely clueless about this — several powerful methods they're missing out on. | Check these out: | 1. copyWithin() | Array copyWithin() copies a part of an array to another position in the same array and returns it without increasing its length.
| const array = [1, 2, 3, 4, 5]; // copyWithin(target, start, end) // replace arr with start..end at target // a. target -> 3 (index) // b. start -> 1 (index) // c. end -> 3 (index) // start..end -> 2, 3 const result = array.copyWithin(3, 1, 3); console.log(result); // [1, 2, 3, 2, 3]
| end parameter is optional:
| const array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; // "end" not specified so last array index used // target -> 0 (index) // start..end -> 6, 7, 8, 9, 10 const result = array.copyWithin(0, 5); // [6, 7, 8, 9, 10, 6, 7, 8, 9, 10] console.log(result);
| const array = [1, 2, 3, 4, 5]; // Copy numbers 2, 3, 4, and 5 (cut off at index 4) const result = array.copyWithin(3, 1, 6); console.log(result); // [1, 2, 3, 2, 3]
| 2. at() and with() | at() came first and with() came a year after that in 2023.
| They are the functional and immutable versions of single-element array modification and access. | const colors = ['pink', 'purple', 'red', 'yellow']; console.log(colors.at(1)); // purple console.log(colors.with(1, 'blue')); // ['pink', 'blue', 'red', 'yellow'] // Original not modified console.log(colors); // ['pink', 'purple', 'red', 'yellow']
| | | I stumbled upon something atrocious when coding the other day. | Do you see it? | | Let's zoom in a bit more: | This line: | | Please don't do this in any language. | Don't await properties. | You're destroying your code readability and ruining the whole concept of OOP. | Properties are features not actions. | They don't do like methods. They are. | They are data holders representing states of an object. | Simple states: | | The fastest way to build AI apps | | We're excited to introduce Writer AI Studio, the fastest way to build AI apps, products, and features. Writer's unique full-stack design makes it easy to prototype, deploy, and test AI apps – allowing developers to build with APIs, a drag-and-drop open-source Python framework, or a no-code builder, so you have flexibility to build the way you want. | Writer comes with a suite of top-ranking LLMs and has built-in RAG for easy integration with your data. Check it out if you're looking to streamline how you build and integrate AI apps. | Start building Writer AI Studio. | Thanks for taking the time to read today's issue. | Don't let the bugs byte,
