Convert array of objects into array of key values

Question

I'm trying to convert an array of object which looks like

var someJsonObj = [
  {id: 0, name: "name", property: "value", otherproperties: "othervalues"},
  {id: 1, name: "name1", property: "value1", otherproperties: "othervalues1"},
  {id: 2, name: "name2", property: "value2", otherproperties: "othervalues2"}
];

to

var someArray = [
  [0,"name","value","othervalues"],
  [1,"name1","value1","othervalues1"],
  [2,"name2","value2","othervalues2"]
]

using .push but what I'm getting are three empty arrays or one array of first values like [0,1,2]

        var someArray=[];
        for(var i=0;i<someJsonObj.length;i++){
            someArray.push(someJsonObj[i].val);
        }

Use Object.values() in es6:

  const someArray = someJsonObj.map( obj => Object.values(obj) );

If you want to guarantee order, use .map(({id, name, property, otherproperties}) => [id, name, property, otherproperties]) instead.

Also, if you don't follow @Xufox advise, I would provide Object.values as is: someJsonObj.map(Object.values) :P

Does that actually work? I tend to worry about problems with binding this when using Object.whatever()

Somehow I'm getting a string instead of array of values. More here: stackoverflow.com/questions/50805989/…
