Iterate through the json object ignoring first object

Hi i m trying to iterate the objects using object.keys where i want to ignore the first object and loop through the remaining items or obejcts

below is the object structure:

controls = {
  101: {
    value: true
  },
  131: {
    value: false
  },
  134: {
    value: false
  },
  136: {
    value: false
  },
  123: {
    value: false
  },
}

here is the code which i am trying to loop and get final result:

const value = Object.keys(controls).forEach((k, i) => {
  if (i > 0) {
    return controls[k].value === false;
  }
})
console.log(value, 'result')

The output should be: -

value should return true --> if all the value are false else return true if one of the object is true, except the first value i.e is id: 101

Ciao, try something like this:

let obj = {
          101: {
            value: true
          },
          131: {
            value: false
          },
          134: {
            value: false
          },
          136: {
            value: false
          },
          123: {
            value: false
          },
        }
        let result = false;
        Object.keys(obj).forEach((k, i) => {
           if (k !== "101") result = result || obj[k].value;
        })
        console.log(result)

A forEach on all keys and a bool result in which store value values.

Depending on implementation order of keys of objects may not be guaranteed so you should be extra careful with it. Assuming that order is what you want it to be, you could use slice and every or some array methods.

const obj = {
  101: {
    value: true
  },
  131: {
    value: false
  },
  134: {
    value: false
  },
  136: {
    value: false
  },
  123: {
    value: false
  },
}

const result = !Object.values(obj).slice(1).every(({value}) => !value);
const result2 = Object.values(obj).slice(1).some(({value}) => value);

console.log({result, result2})
