`['a', 'b']` is an array of strings (`[]string`).
V arrays are homogenous (all elements must have the same type). This means that code like `[1, 'a']` will not compile.
If V is unable to infer the type of an array, the user can explicitly specify it for the first element: `[byte(0x0E), 0x1F, 0xBA, 0x0E]`
V arrays are homogeneous (all elements must have the same type). This means that code like `[1, 'a']` will not compile.
`<<` is an operator that appends a value to the end of the array.
It can also append an entire array.
