I am working on a React Project and need to flatten/cut out the relevant and needed information from an object array.
this is how it look likes:
Under "Person" there is a nested array called "Icds" where there should be exactly one leading diagnosis (=true). How can I filter or reduce this huge array, so I get a similar/new one without too much data inside "Icds" or only one "Icd" where leadingDiagnosis equals true?
Here is one example entry out of 0 to 7:

CodePudding user response：
Icds array with just the IsLeading and _id fields (add more as you see fit):
const icds = calculations.Person.Icds.map((icd) => ({ isLeading, _id }));
Just the Icds object where IsLeading is true. Note that if there are multiple objects where this condition holds, only the first one is returned.
const isLeadingIcd = calculations.Person.Icds.find((icd) => icd.IsLeading === true);
Is this what you're looking for? If not I think it's best you provide an example of the final result you're looking for.
CodePudding user response：
Here is the solution. The steps arre the followings:
- filtering out the true valued Icds nested objects where the IsLeading is true.
- Createing a new Object clone where the data.persons.Icds values are replaced with the filtered array.
If you need the first true valued element you can use find againt filter. Or other condition in the filter.

you could do something like this:

const isLeading = data.calculations.map((cal) => cal.Person.Icds.filter((x) => x.isLeading === true))
Note: In your example there is more than one isLeading that equals true
