return array of key obj in javascript

Question

i have this array obj:

var scenari =[
    {pos:'i4y',azione:('persa','avanti','indietro'),'peso':(0.3,0.4,0.3)},
    {pos:'g4r',azione:('persa','avanti','indietro'),'peso':(0.3,0.4,0.3)}
];

How to retrieve the array in key azione? i try this but is print only 'indietro' and not array

console.log (scenari[0]['azione']);//indietro

I would say, invalid json or object structure. Parenthesis on your "so called" array, are wrong. — Louys Patrice Bessette

You are using ( and ) instead of [ and ]. The key azione is not a JS array. — RyanNHG

The syntax is perfectly valid, the only problem is -- its not used to define an array. — 31piy

Parentheses not define an array and must be use brackets ([]):

var scenari =[
    {pos:'i4y',azione:['persa','avanti','indietro'],'peso':[0.3,0.4,0.3]},
    {pos:'g4r',azione:['persa','avanti','indietro'],'peso':[0.3,0.4,0.3]}
]; 

console.log (scenari[0]['azione']);//indietro

You could also select with console.log(scenari[0].azione); because it is an object property within an array.. :/

You are using () instead of [].

If you use () last value will be the value of key

var scenari =[
    {pos:'i4y',azione:['persa','avanti','indietro'],'peso':(0.3,0.4,0.3)},
    {pos:'g4r',azione:['persa','avanti','indietro'],'peso':(0.3,0.4,0.3)}
]; 

console.log (scenari[0]['azione']);

//If you use () 

//Example:


var ke = ('d','e');

console.log(ke);

You are getting this issue because tuple javascript is treating the data in () as a expression, so to get the result in the way you want you have to use [] or convert your data in string .
