Node.js how to loop through JSON to get values

Question

I'm working with node.js to try and get some values of a JSON using an api, I'm trying to loop through and get the status values in the JSON how would I go about doing this. The JSON is shown below

var serverNamesEurope = [
                        { name: result.Chars.Servers[0].Server[19].Name, status: result.Chars.Servers[0].Server[19].Usage, return: ""},
                        { name: result.Chars.Servers[0].Server[21].Name, status: result.Chars.Servers[0].Server[21].Usage, return: "" },
                        { name: result.Chars.Servers[0].Server[9].Name, status: result.Chars.Servers[0].Server[9].Usage, return: "" },
                        { name: result.Chars.Servers[0].Server[10].Name, status: result.Chars.Servers[0].Server[10].Usage, return: "" },
                        { name: result.Chars.Servers[0].Server[7].Name, status: result.Chars.Servers[0].Server[7].Usage, return: "" },
                        { name: result.Chars.Servers[0].Server[14].Name, status: result.Chars.Servers[0].Server[14].Usage, return: "" },
                        { name: result.Chars.Servers[0].Server[12].Name, status: result.Chars.Servers[0].Server[12].Usage, return: "" }
                    ]

What I want to do is be able to loop through this JSON and then return the status on a seperate line in the console for now.

Hi Cameron, I'd like to suggest that you add what you've tried to the question. Many people are willing to help but would like to see what you've attempted. That said, here's a post on looping through arrays. — alphapilgrim

Try this:

serverNamesEurope.forEach(elem => {
  console.log(elem.status)
})

You could do something like this:

var serverNamesEurope = [
                        { name: result.Chars.Servers[0].Server[19].Name, status: result.Chars.Servers[0].Server[19].Usage, return: ""},
                        { name: result.Chars.Servers[0].Server[21].Name, status: result.Chars.Servers[0].Server[21].Usage, return: "" },
                        { name: result.Chars.Servers[0].Server[9].Name, status: result.Chars.Servers[0].Server[9].Usage, return: "" },
                        { name: result.Chars.Servers[0].Server[10].Name, status: result.Chars.Servers[0].Server[10].Usage, return: "" },
                        { name: result.Chars.Servers[0].Server[7].Name, status: result.Chars.Servers[0].Server[7].Usage, return: "" },
                        { name: result.Chars.Servers[0].Server[14].Name, status: result.Chars.Servers[0].Server[14].Usage, return: "" },
                        { name: result.Chars.Servers[0].Server[12].Name, status: result.Chars.Servers[0].Server[12].Usage, return: "" }
                    ]

console.log(serverNamesEurope.map(record => record.status).join("\n"))

Thanks alot! That was very fast and I'm rather new to this, looks very simple now... When I can accept the answer I will however it's on an interval.

@CameronShearer is a new contributor and while this answers the question doesn't provide the why/how. Teach him to fish IMO.

@alphapilgrim added the reference to .map which I believe would be helpful to @CameronShearer :)
