React JS Tutorial for Beginners to Advanced,
Purpose: The constructor method is primarily used for initializing the component's state and binding event handlers.
It is also used to set up the initial values or state based on the component's props.
The constructor is called before the component is mounted to the DOM.
Syntax:
In a class-based component, the constructor method is defined within the component class.
The constructor takes a props parameter, which is optional. It should be passed to the super() method to call the constructor of the parent class (usually Component).
The state can be initialized within the constructor by assigning an object to this.state.
