How can a "for" loop be used to iterate through the properties of an object?

To iterate through the properties of an object, you should use a for...in loop. This loop iterates over the enumerable properties of an object and allows you to access each property name (key). The for...of loop is used for iterating over iterable objects like arrays. The forEach method is specifically used for arrays, and while loops are generally used for repetitive tasks with a condition.
