El método every ejecuta la función callback dada una vez por cada elemento presente en el arreglo hasta encontrar uno que haga retornar un valor falso a callback (un valor que resulte falso cuando se convierta a booleano). Care must only be taken to make sure that the boolean index has exactly as many dimensions as it is supposed to work with. A bit array (also known as bit map, bit set, bit string, or bit vector) is an array data structure that compactly stores bits.It can be used to implement a simple set data structure.A bit array is effective at exploiting bit-level parallelism in hardware to perform operations quickly.
