HOOKS

 HOOKS WERE A NEW ADDITION IN REACT 16.8

THEY LET YOU USE STATE AND OTHER REACT FEATURES WITHOUT WRITING A CLASS.

INITIALLY, WE USED TO DEFINE COMPONENTS IN THE FORM OF CLASS( CLASS COMPONENTS)

LATER , FUNCTIONS WERE USED (FUNCTION COMPONENT_NAME)

SO, CLASS COMPONENTS HAD SOME ADDITIONAL FEATURES THAT FUNCTIONAL COMPONENTS DIDN'T.

HENCE HOOKS WERE USED TO ACQUIRE THOSE ADDITIONAL FEATURES.

CLASS COMPONENTS = FUNCTIONAL COMPONENTS + HOOKS.
