/*
Write a function to get the first element(s) of a sequence. Passing a parameter n (default=1) will return the first n element(s) of the sequence.

If n == 0 return an empty sequence []

Examples

var arr = ['a', 'b', 'c', 'd', 'e'];
first(arr) //=> ['a'];
first(arr, 2) //=> ['a', 'b']
first(arr, 3) //=> ['a', 'b', 'c'];
first(arr, 0) //=> [];

*/

function first(arr, n=1) {
return arr.slice(0,n)
}
