Question

Please somebody guide me in the right way

myObject = {"Timer13":{"Arm":0,"Mode":0},"Timer14":{"Arm":1,"Mode":1}}

And i need get this array

[{"timer":"Timer13", "Arm":0,"Mode":0},{"timer":"Timer14","Arm":1,"Mode":1}]

I tried several ways, i dont get it;

Maybe try appending a key and add the rest of the elements to the object before returning from the map.

var myObject = {"Timer13":{"Arm":0,"Mode":0},"Timer14":{"Arm":1,"Mode":1}}

var result = Object.keys(myObject).map(elem => {
    return {timer: elem, ...myObject[elem]}
})

console.log(result)

Nice answer. You can return an object from an arrow function by surrounding it in parens to avoid the return statement: Object.keys(myObject).map(elem => ({timer: elem, ...myObject[elem]}))

You could get the entries and map new objects by assigning the parts.

var object = { Timer13: { Arm: 0, Mode: 0 }, Timer14: { Arm: 1, Mode: 1 } },
    array = Object
        .entries(object)
        .map(([timer, values]) => Object.assign({ timer }, values));

console.log(array);

.as-console-wrapper { max-height: 100% !important; top: 0; }

You can use reduce to achieve that playing with Current Value (curr) an Accumulator (all) also destructing your array can be helpful for a cleaner code. [timer,obj] timer : curr[0] and the obj is curr[1]

obj = {
  "Timer13": {
    "Arm": 0,
    "Mode": 0
  },
  "Timer14": {
    "Arm": 1,
    "Mode": 1
  }
}

const res = Object.entries(obj).reduce((all, [timer, obj]) => {
  all.push({
    timer,
    ...obj
  })
  return all;
}, [])


console.log(res)
