Quick start

A usage example from the v8-to-istanbul README.

const v8toIstanbul = require('v8-to-istanbul')
// the path to the original source-file is required, as its contents are
// used during the conversion algorithm.
const converter = v8toIstanbul('./path-to-instrumented-file.js')
await converter.load() // this is required due to async file reading.
// provide an array of coverage information in v8 format.
converter.applyCoverage([
  {
    "functionName": "",
    "ranges": [
      {
        "startOffset": 0,
        "endOffset": 520,
        "count": 1
