Where this matters
Two separately loaded records can contain the same fields without being the same object. Compare specific fields when that is your intended question.
JavaScript · read-only example
console.log({ id: 1 } === { id: 1 });Read the full explanation
Each object literal creates a separate identity. Strict equality does not compare object contents recursively.
Trace the code
- Each pair of braces creates a fresh object.
- Strict equality checks whether both operands refer to the same object, not whether their id properties match.
- No recursive property comparison takes place.
Why the other predictions differ
true— Matching properties do not make separate objects the same object.TypeError— Comparing object references is valid JavaScript.
false
Reading this explanation does not record mastery. A correct submitted attempt can do so, including after review.
Change one thing
Store one object and give it a second name, then compare those references.
Predict the result, then run this self-contained snippet in your browser’s developer console. It uses only sample values and makes no network requests.
const first = { id: 1 }; const second = first; console.log(first === second);Check the variation’s output
true
