Associative array/Merging
Associative array/Merging is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
- Task
Define two associative arrays, where one represents the following "base" data:
| Key | Value |
| "name" | "Rocket Skates" |
| "price" | 12.75 |
| "color" | "yellow" |
And the other represents "update" data:
| Key | Value |
| "price" | 15.25 |
| "color" | "red" |
| "year" | 1974 |
Merge these into a new associative array that contains every key found in either of the source ones. Each key should map to the value in the second (update) table if that exists, or else to the value in the first (base) table. Obviously this should be done in a way that would work for any data, not just the specific data given here, but in this example the result should be:
| Key | Value |
| "name" | "Rocket Skates" |
| "price" | 15.25 |
| "color" | "red" |
| "year" | 1974 |
MiniScript
MiniScript supports merging maps with the `+` operator. <lang MiniScript>base = {"name":"Rocket Skates", "price":12.75, "color":"yellow"} update = {"price":15.25, "color":"red", "year":1974}
result = base + update
print result</lang>
- Output:
{"color": "red", "name": "Rocket Skates", "price": 15.25, "year": 1974}
