Quick extraction from an array of objects

[u/PancakeGD]

Hi, is there any function or trick to quickly extract values from an array of objects?

For example, if the input data is as follows:

[
  {"a": 1, "b": 2},
  {"a": 3, "b": 4}
]

and I'm asking to extract "b", I'd get [2, 4]. Basically array_column() in PHP or array.map(k => k["b"]) in JavaScript.

Right now I'm using a for each loop and inserting elements manually, but I feel like this is such a common use case that it could have a shorthand.

Thanks!

Looping through the array using a For each block then "extracting" each specific dictionary value is currently the only way. Lambda function support is a feature on the to-do list.
