Problem Statement

Collections are abstractions to represent sets of values.
In statically-typed languages, the values are typically of a common data type.

Create a collection, and add a few values to it.

Let's start with the solution:

{"a": 1} == {a: 1}

"a" as $key | 1 as $value | {($key): $value}

[0,1,2] | .[0] = 10
