Linking a JSON object to JavaScript Comparison and Logical Operators

Wait... What are you trying to achieve here?

I think you're after something like this?

var json = {9: "1", 2: "4", 6: "5", 7: "3", undefined: ""};
var questionId = 9;
var answer = 2;
var comparison = '<';
var result = null;

if (json.hasOwnProperty(questionId)) {
    if (comparison === '<') {
        result = json[questionId] < answer;
    }
  
    if (comparison === '>') {
        result = json[questionId] > answer;
    }
  
    if (comparison === '=') {
        result = json[questionId] == answer;
    }
}

console.log(result);

Hello, I have this and such keys 9 < 2 || 7 < 3 && 6 == 4 or 10 < 5 || 7 < 4 && 1 == 4 could be any logic here. This is the logic to use to compare the users data in form of a JSON object.

The object is the form of {10: "1", 2: "4", 6: "5", 7: "3", undefined: ""}

So using the logic above, e.g. 10 < 5 || 7 < 4 && 1 == 4, get the value 10 and check it's corresponding value in the the object key/value which gives 1. Hence the new comparison becomes 1< 5 || 7 < 4 && 1 == 4

Do the same for the next comparison 7 < 4. Which should become 3 < 4 where 3 is the value to the key 7 on the object.

When all is done on the logic and comparison operations, now eval().

Thanks

I honestly have no clue what your question is right now...

What have you tried so far yourself?

Sounds like a cut and paste from a homework assignment
