[Eslint]: Wrong detection for no-unused-vars rule

[Anonymxtrix]

Expected Behavior

function initCurveBuffer(gl: any, func: (t: number) => Point, num: number) { ... }

In the function above, if func is used in the function, eslint should not be highlighting any errors.

Current Behavior

Eslint saying that t is defined but never used, although func is used somewhere in the function.

Steps to Reproduce

Please provide detailed steps for reproducing the issue.

1. Open your favourite editor. (ie. VSCode)
2. Write the following function in any .ts file under src directory.

function initCurveBuffer(gl: any, func: (t: number) => Point, num: number) {
  const num = 0;
  for (let i = 0; i <= num; i += 1) {
    const point = func(i / num);
  }
}

3. Enjoy the erroneous (and irritating) eslint errors!

Look here for possible solution. It seems like we configured eslint airbnb wrongly since we used airbnb instead of airbnb-typescript stated here.
