Function, to Test whether the Element is present in the Array

Example 1:

const list = [{"id":1, "data":"a"},{"id":2, "data":"b"},{"id":3, "data":"c"}]
elementInArray("b", list, "data") // => true
elementInArray(5, list, "data") // => false
elementInArray("b", list, "property_not_in_data") // => false

Example 2:

const list = [{"id":1, "data":["a"]},{"id":2, "data":["b"]},{"id":3, "data":["c"]}]
elementInArray("b", list, "data/0") // => true
elementInArray("d", list, "data/0") // => false
elementInArray("b", list, "data")   // => false <- Path doesnt contain 'b'
elementInArray("b", list, "data/1") // => false <- Path wrong, no elements there
