Tests:

  • array.includes

     
    var result = [];
    ​
    for (const id of idsFind) {

    }
    ​
    return result

  • Object.prototype.hasOwnProperty

     
    var result = [];
    ​
    for (const id of idsFind) {
      if (Object.prototype.hasOwnProperty.call(entities, id)) {
        result.push(entities[id])
      }
    }
    ​
    return result
