   VS Code Extension to skip the noisy web tools (JSON Prettify, and more)▲24

   Hi HN, Simple online tools on the web have become unnecessary greedy. For example, * https://jsonformatter.org/ displays 7 ads on page load * https://convertcase.net/ had 4 ads plus a Google Vignette. And many more sites do the same thing. It's just noisy, which is why I created this VS Code Extension where you don't need to even leave your editor for your small web operations. I also built a Desktop app and an online version, which can be reached or downloaded at smallonlinetools.net. Both of which will be ad-free forever. So far smallonlinetools.net has over…

    A stab at building my own string diffing library▲29

    Took a stab at building my own string diffing JS package. I built an interactive demo for TypeIt’s website (https://typeitjs.com/build-your-own) a while back.
