This is a port of this blog post to javascript. The one annoying issue with it is that you need to install node-fetch somehow (or put this script somewhere that has access to node-fetch). I could adapt this to use no deps, but it'd be longer and uglier.

const {strPosToUni, uniToStrPos} = require('unicount')

// The cursor position (input and output) are specified in JS string
// offsets here.
function transformJSPosition(cursor /*: number*/, doc /*: string*/, op /*: TextOp*/) {
  let prePos = 0, postPos = 0 // string index in doc.

  for (let i = 0; i < op.length && cursor > postPos; i++) {
    const c = op[i]

In case anyone else wants to play with Zig on webassembly, here's what you need to do to make it work on a mac today.

1. Get LLVM 7 compiled with webassembly support.

You'll need LLVM to output to the WASM target. This has just been added by default in trunk, so if LLVM >7 is available, you might be able to just brew install llvm.

If you have wasm support already you should see:

$ llc --version
