JavaScript Objects: Why are value1.a[x] and value2.b[x] returned as undefined since a[x] = a and b[x] = b which are properties of value1 and value2?

value1 = {a:5, b:6}, value2 = {a:8, b:7};  let a = Object.keys(value1), b = Object.keys(value2);    for (let x = 0; x < a.length; x ++) {       if (a[x] === b[x] && value1.a[x] === value2.b[x]) {        console.log(a[x], b[x], value1.a[x], value2.b[x]);      }    }  // -> a, a, undefined, undefined  

P.S. I know the other ways to compare objects; just wanted to find out why this doesn't work.
