Return value of an object from array of object

Question

I have an array of object

const data = [{id:"1", "name":"ab", value:100, doubleval:'344'},{id:"2", "name":"ab", value:200,doubleval:'122'},{id:"1", "name":"bc", value:100, doubleval:'123'},{id:"1", "name":"bc", value:300, doubleval:'44'}]

so I want to get value from this So I tried using lodash

return _.filter(data, (item) => {
            return (item === 'ab') ? item?.value : budgetRangePlan?.doubleval
      })

This returns an array of object,

here I was expecting value as 100 and 200 respectively.

How do I fix this ?

map returns an array of object as well.. I wanted to get the exact value — ganesh kaspate

Filter is for collect element fits a boolean condition. For your code I think that you could try

let rs = data.map((data) => (data.name == 'ab' ? data.value : data.doubleval))

This should help you:

const data = [{id:"1", "name":"ab", value:100, doubleval:'344'},{id:"2", "name":"ab", value:200,doubleval:'122'},{id:"1", "name":"bc", value:100, doubleval:'123'},{id:"1", "name":"bc", value:300, doubleval:'44'}]

let result = data.map(a => a.name == 'ab' ? a.value : a.doubleval);

console.log(result)

Actually I want to return a single value for this

I edited the answer. Does it fix your problem now?

Forget that edit, it won't return a single value. I'm a bit confused...:D You want to return either the value 100 or 200 if name is 'ab'?
