Learning to extract information from a JSON file with various key and value combinations

I am facing a challenge with my JSON data file, which contains UserIDs as keys and Passwords as values. My goal is to use JavaScript for validation by reading this JSON file. The structure of my JSON is as follows:

IDsNPass = '[{"A":"A15"},{"B":"B15"},{"C":"C15"}]';

While I know how to access the data in JavaScript when the keys remain constant, the issue here is that the keys in my JSON are not consistent. Any guidance on how to approach this problem in JavaScript would be greatly appreciated!

Answer №1

Initially, the layout of your design needs improvement.

In case you have a single object with an ID-password mapping, you can implement it like this:

let idPwd = JSON.parse(IDsNPass)

for(let entry in idPwd) {
  for(let key in entry) {
    console.log(key)
    console.log(entry[key])
  }
}
