With these objects
let myObjectA = {"fruits": {"item1":1, "item2":1}, "vegetables": {"item3":1, "item4":1} },
myObjectB = {"fruits": {"item5":1, "item6":1} };
I need to do the same for loop for obtaining the keys, but when I do the same for loop
for(var i in myObjectA){
print(myObjectA[i]);
}
for(var j in myObjectB){
print(myObjectB[j]);
}
In the first loop I get the two items, but in the second I get undefined
How do I get the fruits result, even when it is only one key in the object? I need a dynamic for loop because I don't know in advance if I'll get a one or two keyed objects
It's a typo as mentioned, but for reference, you can also obtain object keys with... wait for it... Object.keys :)
let myObjectA = {
"fruits": {
"item1": 1,
"item2": 1
},
"vegetables": {
"item3": 1,
"item4": 1
}
},
myObjectB = {
"fruits": {
"item5": 1,
"item6": 1
}
};
let keys = Object.keys(myObjectA);
console.log(keys);
keys.forEach(k => {
let item = myObjectA[k];
let subkeys = Object.keys(item);
console.log(`subkeys of ${k}`, subkeys)
})You are passing i in myObjectB[i]
for(var i in myObjectA){
print(myObjectA[i]);
}
for(var j in myObjectB){
print(myObjectB[j]); // correction pass j not i
}
