<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>

Script Preparation code:

window.case1 = new Proxy({}, {
  get(t, p, r) {
    if (typeof p === 'string' && !isNaN(p)) {
      return +p
    }
    else {
      return Reflect.get(t, p, r)
    }
  }
});
window.case2 = new Proxy({}, {
  get(t, p, r) {
    if (/^\d+$/.test(p)) {
      return +p
    }
    else {
      return Reflect.get(t, p, r)
    }
  }
});
window.case3 = new Proxy({}, {
  get(t, p, r) {
    if (typeof v === 'number' && isFinite(v)) {
      return +p
    }
    else {
      return Reflect.get(t, p, r)
    }
  }
});
window.gabage1 = 0;
window.gabage2 = 0;
window.gabage3 = 0;

Tests:

isnan
gabage1 =+ case1[_.random(0, 1e3, false)];
regex
gabage2 =+ case2[_.random(0, 1e3, false)];
typeof
gabage3 =+ case3[_.random(0, 1e3, false)];
