VisualizaçõesGet parent object, by nested property
I have the following object, an array with databases, each containing a collection of tables, each containing a collection of columns.
I want to obtain the parent table, given the Id of a column and tried to avoid iterating over the collection. Just a very simple clean single line.
I was initially trying but quickly was challenged by the fact Tables is not an array but a collection which doesn't support .some statements.
let table = schema.find((database,index) => database.Tables.some((column,index) => column.Id === 1234));
Is there a smart way or conversion trick that I have overlooked that prevents me from having to iterate the entire structure?

Use Object.values() to get an array of columns from your Tables object:
let table = schema.find(database => Object.values(database.Tables).some(column => column.Id === 1234));
Alternately, you could use Object.keys() and write it like this:
let table = schema.find(database => Object.keys(database.Tables)
.some(columnName => database.Tables[columnName].Id === 1234));
