@ symbol in the key in JSON is giving error while accessing it

Question

I have following JSON element.

    "myObj":[
      {
         "@type":"xzy",
         "data" :"pqr"
      }
     ]

I am accessing a value inside the array using the key as follows

var data = myNode.filter(x => x.@type=='xyz').map(y=>y.data)

But I canot do it becuase of the @ symbol in the key. I tried surrounding it with '

var data = myNode.filter(x => x.'@type'=='xyz').map(y=>y.data)

but again it fails. @ symbol is valid in JSON. So, I should be able to access it. How can I do this in Javascript? Appreciate your input

did you tried using `[ ]`, var data = myNode.filter(x => x['@type'] == 'xyz').map(y=>y.data) — Akhil Aravind, Jul 17 '18 at 09:54

Instead of:

var data = myNode.filter(x => x.'@type'=='xyz').map(y=>y.data)

Use this:

var data = myNode.filter(x => x['@type']=='xyz').map(y=>y.data)

Square bracket notation allows access to properties containing special characters and selection of properties using variables.
