Convert array of objects into array of properties [duplicate]

Answer 1

You could do something like this:

var len = someJsonArray.length, output = [];
for(var i = 0; i < len; i++){
   output.push(someJsonArray[i].id)
}

console.log(output);

Answer 2

You can do this way:

var arr = [];
for(var i=0; i<someJsonArray.length; i++) {
    arr.push(someJsonArray[i].id);
}

Answer 3

A more minimal example (ES6 onwards):

someJsonArray.map(({id}) => id)

Answer 4

Use .map() function:

finalArray = someJsonArray.map(function (obj) {
  return obj.id;
});

Snippet

var someJsonArray = [
  {id: 0, name: "name", property: "value", therproperties: "othervalues"},
  {id: 1, name: "name1", property: "value1", otherproperties: "othervalues1"},
  {id: 2, name: "name2", property: "value2", otherproperties: "othervalues2"}
];
var finalArray = someJsonArray.map(function (obj) {
  return obj.id;
});
console.log(finalArray);

The above snippet is changed to make it work.
