So, I have this answer I want to extract, among other things, the subjects, to test against other answers.
{
"subject": {
"pe": {
"total": 23,
"passed": 2,
"failed": 1,
},
"maths": {
"total": 23,
"passed": 19,
"failed": 4,
},
"history": {
"total": 20,
"passed": 17,
"failed": 3
}
}
}
How do I get only the subjects?? Like:
{
"pe",
"maths",
"history"
]
