getAllBeforeFirst(value, array): any[]

Returns everything before first instance of value in array. Does not modify array.

getAllBeforeLast(value, array): any[]

Returns everything before last instance of value in array. Does not modify array.

For both functions, value cannot be an object. Arrays are OK.

let arr = [1, 2, 3, 4, 5, 6, 1, 2, 3, 4, 5, 6];
getAllBeforeFirst(6, arr);
   // --> [1, 2, 3, 4, 5]

getAllBeforeLast(6, arr);
   // --> [1, 2, 3, 4, 5, 6, 1, 2, 3, 4, 5]
