⏯ Playground Link
Playground currently doesn't show the error:
💻 Code
function deepEquals<T>(a: T, b: T): boolean {
if (typeof a !== 'object' || typeof b !== 'object' || !a || !b) {
return false;
}
if (Array.isArray(a) || Array.isArray(b)) {
return false;
}
if (Object.keys(a).length !== Object.keys(b).length) { // Error here
return false;
}
return true;
}🙁 Actual behavior
The calls to Object.keys generate errors:
No overload matches this call.
Overload 1 of 2, '(o: {}): string[]', gave the following error.
Argument of type 'T' is not assignable to parameter of type '{}'.
Overload 2 of 2, '(o: object): string[]', gave the following error.
Argument of type 'T' is not assignable to parameter of type 'object'.
🙂 Expected behavior
No errors
