Lodash Dependency

May I suggest removing Lodash as a dependency?

The single call to the Lodash isEqual function could be probably replaced with a simple local implemention:

function isEqual(a: any, b: any) {
  if (a === b) {
    return true;
  }
  if (a === null && b === null) {
    return true;
  }
  if (typeof (a) !== typeof (b)) {
    return false;
  }
  if (typeof (a) === 'object') {
    // Array
    if (Array.isArray(a)) {
      if (!Array.isArray(b)) {
        return false;
      }
      if (a.length !== b.length) {
        return false;
      }
      for (let i = 0; i < a.length; i++) {
        if (!isEqual(a[i], b[i])) {
          return false;
        }
      }
      return true;
    }
    // Hash table
    const keys = Object.keys(a);
    if (keys.length !== Object.keys(b).length) {
      return false;
    }
    for (let i = 0; i < keys.length; i++) {
      if (!b.hasOwnProperty(keys[i])) {
        return false;
      }
      if (!isEqual(a[keys[i]], b[keys[i]])) {
        return false;
      }
    }
    return true;
  }
}

No files or tests are named. Start by locating the sole Lodash isEqual call and the dependency declaration, then run the existing test suite. Done means Lodash is no longer required and the existing equality behavior remains covered by passing tests.
