async function asyncSumOfSquares() {
  const numbers = [1, 2, 3, 4, 5];

  const result = await numbers.reduce(async (acc, num) => {
    const currentSquare = await Promise.resolve(num * num);
    return (await acc) + currentSquare;

Why JavaScript is so hard 😂

🌕 ✌️ I built my own Google (sort of...) with Text Transformers and Qdrant Vector Database Building content search functionality for Next.js project almost always requires deep understanding of how the text similarity search works. Nowadays we have text transformer AI Models from HuggingFace and Vector Databases that easily could be integrated to Next.js giving the powerful similarity search functionality with a blasting speed! This video below explains this in detail. Tigran Tech

async function asyncArrayOperations() {
  const array1 = [1, 2, 3];

    return await arr.reduce(async (acc, num) => {
      return (await acc) + num;
    }, Promise.resolve(0));
  }));

  console.log(result);

🌲 Tinybench: A Tiny, Simple Benchmarking Library No dependencies, but uses whatever precise timing capabilities are available (e.g. process.hrtime or `peformance.now`). You can then benchmark whatever functions you want, specify how long or how many times to benchmark for, and get a variety of stats in return. TINYLIBS

const matrix = [
  [2, 4],
  [6, 8],
];

const result = matrix.reduceRight((acc, row) => acc.concat(row.map(num => num * 2)), []);

console.log(result);

⛽️ npm in Review: A Retrospective in Numbers From Socket comes a look at the past year from the perspective of the npm registry, focused largely on statistics (2.5 million live packages!), including download numbers, popular packages, as well as some ‘quirky facts’ like the package with the most maintainers (554, if you're wondering.)

function* fibonacci() {
  let a = 0, b = 1;

const fibSequence = Array.from({ length: 5 }, () => fibonacci().next().value);

➡️ Survay from Eindhoven University Mentorship is a process in which a more experienced or more knowledgeable person (a mentor) helps to guide a less experienced or less knowledgeable person (a mentee). Relatively little is known about the practice of mentorship within software development contexts. For that reason, we would like to ask you a few questions about what mentorship means to you and what matters most in mentoring relationships. The survey is expected to take 10-15 minutes to complete. Only the researchers involved in this study will see your responses. Your participation in this study is voluntary. You also do not have to answer any question that makes you uncomfortable. Participants must be 18+. For questions or comments about the survey, please reach out to Dr. Reed Milewicz (rmilewi@sandia.gov) or Dr. Alexander Serebrenik (a.serebrenik@tue.nl). Clicking submit indicates that you consent to the use of your survey response data in our study. For every survey completed, we pledge to donate $1 USD to an open-source 501(c)(3) non-profit organization of your choice.

StringZilla v3 is starting to look serious! Crushing C++ standard library by 3-20x is one thing... But superseding LibC implementations and potentially bringing them to other programming languages is what will make this library truly special🔥 Any Rust and JS developers with C experience willing to implement the wrappers?
