Simple script to sort the google drive files by size

[...document.getElementsByClassName("a-t-J a-Wa-ka l-oi-cc l-t-Q a-t-J-yl")]
  .map(element => {
    const [
      size,
      unit
    ] = element.childNodes[3].childNodes[0].childNodes[1].childNodes[0].innerText.split(
      " "
    );
    const SIZES_KB = { MB: 1024, GB: 1048576, KB: 1 };
    return {
      size: Number(size) * SIZES_KB[unit],
      node: element
    };
  })
  .sort((elementA, elementB) => elementB.size - elementA.size)
  .forEach(element => {
    const files = document.getElementsByClassName("a-t-J-Rf")[0];
    files.appendChild(element.node);
  });

When lodash is too much

It is not always necessary to use the well-known lodash utility library to do some basic operations with arrays and javascript objects.

Get safe object properties

function isObject(object) {
  return object && typeof object === "object";
}
function hasKey(object, key) {
  return key in object;
}

function safe(object) {
  return new Proxy(object, {
    get: (target, name) => {
      if (!hasKey(target, name)) {
        return "undefined";
      }
      if (!isObject(target[name])) {
        return target[name];
      }
      return safe(target[name]);
    }
  });
}

let's try...

const objectDeep = { a: { b: "x" } };
console.log(objectDeep.a.b);
// x
console.log(objectDeep.c.d);
// TypeError: Cannot read property 'd' of undefined
console.log(safe(objectDeep).a.b);
// x
console.log(safe(objectDeep).c.d);
// undefined

Get object's array unique

function isEqual(objectA, objectB) {
  return JSON.stringify(objectA) === JSON.stringify(objectB);
}

function unique(array) {
  return array.reduce((uniqueArray, currentElement) => {
    const isDuplicated = uniqueArray.find(element =>
      isEqual(element, currentElement)
    );
    return isDuplicated ? uniqueArray : [...uniqueArray, currentElement];
  }, []);
}

let's try...

console.log(unique([{ a: "x" }, { a: "z" }, { a: "x" }]));
// [ { a: 'x' }, { a: 'z' } ]

Get array one dimension less

function flat(array) {
  return [].concat.apply([], array);
}

let's try...

console.log(flat([["a", "b"], ["c", "d"]]));
// [ 'a', 'b', 'c', 'd' ]

Get clone object deep

function cloneDeep(object) {
  return JSON.parse(JSON.stringify(object));
}

let's try...

const objectDeep = { a: { b: "x" } };

const objectDeepClonedAssign = Object.assign(objectDeep);
objectDeep.a.b = "assign";
console.log(objectDeep);
// { a: { b: "assign" } }
console.log(objectDeepClonedAssign);
// { a: { b: "assign" } }

const objectDeepCloned = cloneDeep(objectDeep);
objectDeep.a.b = "deep";
console.log(objectDeep);
// { a: { b: "deep" } }
console.log(objectDeepCloned);
// { a: { b: "assign" } }
