Java script get an object array filtered only with certain properties : I have an array of objects(object is `<Employee>` type) as shown below,

    [{i: "MCA001", j: 4, n: "KEITH G MCALLISTER", m: null, a: 1, …}
    , {...}]

i want this <Employee> object array filtered with certain properties,
for an instance, filtered array should have few properties,

    [{i:.., j:.., a:..}]

i'm trying to use filter and map functions and still no success.
Appreciate if anyone can help me to figure this out.
Thank you very much.
