javascript check if dictionary

Question

I have a simple program like:

var a = {\'a\': 1, \'b\': 2}
console.log(a)
console.log(a instanceof Array)
console.log(a.constructor instanceof Array)
         


        

Answer 1

Would that work ?

function isDictObj(obj: any) {
  try {
    const test = {...obj}
  } catch(err) {
    return false
  }
  return true
}

My logic is that if it is a dictionnary object (key:values), then using spread operator with {} should work, otherwise throw an exception
