Test 1
let obj = { 'a': 1, 'b': 2, 'c': 3 }; let condVal = 2; let result = {}, key; for (key in obj) { if (obj.hasOwnProperty(key) && condVal == obj[key]) { result[key] = obj[key]; } }
Test 2
let obj = { 'a': 1, 'b': 2, 'c': 3 }; let condVal = 2; Object.keys(obj) .filter( key => condVal == obj[key] ) .reduce( (res, key) => (res[key] = obj[key], res), {} );
