React useReducer Hook | To-Do App| State Management in React Functional Components

useReducer Hook is another built in Hook in React to handle complex state management.
if your component has simple states like string, boolean then useState Hook is sufficient and you used use this only but as project grow, complexity also increase and in that case handling states with useState will be tough, there useReducer Hook will be better option.
useReducer takes 3 parameters ,
1) reducer function (required parameter ): redux is a pure function that takes previous state and action an argument and return the next state.
2) Initial State:(required parameter ) With this state, you reducer will initialise
3) init function(optional): if you pass third parameter, then it will initialise the initial state lazily.
