/*
    Some is function which takes a callback function as input 
    It returns true as soon as the condition of the callback is satisfied 
    i.e if array is [5,7,9,11,15,13,10,31,21,24,54,100];
    And condition inside the callback is if(value%2==0){return true}, then as soon as the callback is on 10 i.e first even number in this array it will return true.
    In other words some will return true even if one element satisfies the condition inside the callback.


    Whereas Every will return true only when every element satisfies the condition inside the callback. Else it will return false
