javascript loop object

  key2: "value2",
  key3: "value3"
}

Object.keys(obj).forEach(key => {
    console.log(key, obj[key]);
});
// key1 value1

going through every attributes of an object javascript

let a = {x: 200, y: 1}
let attributes = Object.keys(a)
console.log(attributes)
//output: ["x", "y"]

loop through json array and get key name

function iterateNodes(data) {
    for (var i = 0, l = data.nodes.length; i < l; i++) {
        var node = data.nodes[i];

        console.log(node.name);

        if (node.nodes) {
            arguments.callee(node);
        }
    }
}

iterateNodes(data);
