Convert a object in javascript to json object

Question

i have a jsonStrng like var sourceJsonStr= {"foo":25,"xyz":49}; I want similar in JSON object like var targetStrJson = [['foo', 25], ['xyz', 49]]. How do convert sourcejson to targetjson in javascript.

you have an object, and you want a nested array ... there is no JSON involved in the question or any potential answer — Jaromanda X, Jan 24 '17 at 05:59

Here's one way to do it:

var source = {"foo": 25, "xyz": 49};
var target = Object.keys(source).map(key => [key, source[key]]);

console.log(target);

Another way to do this.

var sourceJsonStr= {"foo":25,"xyz":49}; 
var targetStrJson = [];
for(var key in sourceJsonStr){
   targetStrJson.push([key, sourceJsonStr[key]]);
}

console.log(targetStrJson);

Using .map in es5

var sourceJsonStr = {
  "foo": 25,
  "xyz": 49
};
var targetStrJson = Object.keys(sourceJsonStr).map(function(key){
  return [key, sourceJsonStr[key]];
});

console.log(targetStrJson);
