What results will be output when comparing primitive and object types using == and ===?

true false true

false false true

true false false

When comparing primitive and object types using the `==` and `===` operators in JavaScript, the behavior is distinct and can lead to different output results.

When using the `==` operator (loose equality), JavaScript attempts to convert the operands to the same type before making the comparison. For example, if a primitive value is being compared to an object, the object is converted to a primitive value (typically a string representation or number) based on its value. If they are equal after this type coercion, `==` will return `true`.

On the other hand, the `===` operator (strict equality) checks for both value and type without performing any type conversion. Therefore, if the values being compared are of different types (such as a primitive type and an object), `===` will always return `false` since they do not share the same type.

In the context of the choices given, the result of comparing a primitive type with an object using `==` yields `true` when coercion occurs (assuming the object can be converted to match the primitive value), and `false` when using `===`, as they are unequal in type. When comparing two primitives of the same type, both `==`
