this is very simple, just do this :

let fileName = "test.cv";
data.docs.forEach(item => {       
    if (fileName == item.title) {
        console.log("this is the file your are looking for ", item);
    }
})

You can do something like

const result = data.docs.map(doc => doc.title);

This contains only the titles, then result.includes("mytext") to check if your text exists in the array.

In order to save titles in new array you should use "map" array function:

const result = data.docs.map(({ title }) => title)

To print titles use forEach function which doesn't create new array just iterate over this one:

data.docs.forEach(({ title }) => {
  // here you can do the title checking
  console.log(title)
})
