Answer 1

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); 

Answer 2

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);
