Examples

has(1, [1,2,3]); // --> true

// Notice that arrays don't need to be identical via `===` to match:
has(
    [2,3],
    [1, [2,3], 4, 5]
);
// --> true

// Objects do need to be identical via `===` to match:
has(
    {name: 'joe'},
    [1, 2, 3, {name: 'joe'}]
);
// --> false

let obj =  {name: 'joe'};
has(
    obj,
    [1, 2, 3, obj]
);
// --> true

has(
    [2, 3],
    [1, 2, 3, 4, 5]
);
// --> false

hasAdjacent(
    [2, 3],
    [1, 2, 3, 4, 5]
);
// --> true

hasAdjacent(
    ['a','b','c'],
    ['a','b','d','c']
);
// --> false


hasAny(
    ['d', 'a'], 
    ['a', 'bb', 'c', 'cc']
);
// --> true

hasAny(
    ['d', 'a'], 
    ['aaa', 'bb', 'c', 'cc']
);
// --> false

hasAll(
    [1, 3, 5],
    [1, 2, 3, 4, 5, 6, 7]
);
// --> true

hasAll(
    [1, 3, 5],
    [1, 2, 3, 4, 6, 7]
);
// --> false
