ESLint uses similar thing to Ranges

Well, sort of.

If you check the ESLint API, the verify() will return a range key:

{
  fatal: false,
  ruleId: "semi",
  severity: 2,
  line: 1,
  column: 23,
  message: "Expected a semicolon.",
  fix: {
    range: [1, 15], // <---- this
    text: ";"
  }
}

The string indexes are the same — they are also placed in an array — the only difference is ESLint explicitly tells what to insert using a separate key.

If ESLint marked a finding like this:

{
  range: [1, 15],
  text: ";"
}

Ranges would mark it shorter:

[[1, 15, ";"]];

Very similar!
