[
    1, 2, 3, 4,
    5, 6, 7, 8
]

Steps Description

1. Declare three variables a, b and c
2. Initialize three variables with array value respectively a = [1,2,3,4,5], b = [6,7,8] and c = [...a,...b]
3. The spread(...) operator converts multiple arrays into a single array.
4. The value of c variable is displayed with the help of console.log inbuilt function
