How to iterate JSON object with same key-CodePudding

I have a API response, which is like the below code

const res = {

"a" : {},
"a" : {}

}

CodePudding user response：

This is not possible. In JSON, there is no error if you use the same name for multiple keys, but the last key with the same name will be used. I suggest using an array for the values for a key.

E.g.:

const res = {
    "a" : {},
    "a" : {}
}

would be

const res = {
    "a" : [{}, {}]
}

Then you could iterate on the list.

CodePudding user response：

if "a" isn't used to identify it's value, it shouldn't be a key. You could restructure you JSON to look like this:

const res = [
  ["a", {}],
  ["a", {}]
]

and then iterate over it using:

for(let [k,v] of res)
  print(k,v)
