In Python if you have a function like this:

def my_function(param1, param2, param3):
  print (param1, param2, param3)

And you have dictionary like this:

my_dict = {"param1": 1,
           "param2": 2,
           "param3": 3}

Then you can destructure a dictionary and pass the values in the dictionary to the function like this:

my_function(**my_dict)

which basically calls my_function(1, 2, 3)

Is there any way you can do this in javascript? I know you can destructure a list using ... but I am not sure how I can desctructure a dictionary. Please help.

Thanks!

That was an easy one ;)) – georg Nov 03 '18 at 18:44
JavaScript objects are unordered and JavaScript doesn't have named function parameters, so even if it supported that syntax it would not be able to define which argument goes into each parameter position. – Paul Nov 03 '18 at 19:39
