Retrieve information in JSON format from a document

I'm trying to extract data from a JSON file without knowing the exact location of the data. Here is an example JSON:

    var names= [
{
 "category":"category1" ,
     "name1":"david",
     "name2":"jhon",
     "name3":"peter"
},
{
 "category":"category2" ,
     "name1":"Smith" ,
     "name2":"Anna",
}
]

Let's say I have a string variable:

var str='category2';

How can I access the value of category2.name1 using the variable? I want to avoid hardcoding names[1].name1 and also steering clear of using a for loop.

Answer №1

If you need assistance, there are predefined functions that can be useful. For instance:

let filteredResults = items.filter(function(item, index, array) { 
  return item.type === target;
});

Your desired outcome will consistently appear in filteredResults[0].property when filteredResults.length > 0.
