1. Syntax:

   • Regular Function:

        function regularFunction(parameter) {
         // function body
       }
     

   • Arrow Function:

       const arrowFunction = (parameter) => {
         // function body
       };
     

2. this Binding:

   • Regular Function:

     • Has its own this binding, which is determined by how the function is called.

   • Can be influenced by methods like bind, call, or apply.

   • Suitable for methods in objects or constructors.

   • Creates a new this context in every function call.

   • Example:

       function regularFunction() {
         console.log(this);
       }
     

   • Arrow Function:

     • Lexically binds this to the enclosing scope, which means it inherits this from the surrounding code.

     • Well-suited for concise functions and avoiding issues related to changing this context.

     • Example:

         const arrowFunction = () => {
           console.log(this);
         };
       

3. Arguments Object:

   • Regular Function:

     • Has access to the arguments object.

     • Example:

        function regularFunction() {
          console.log(arguments);
        }

• Arrow Function:

  • Does not have its own arguments object. It inherits the arguments from its enclosing scope.

  • Example:

        const arrowFunction = (...args) => {
          console.log(args);
        };

1. Use Cases:

   • Regular Function:

     • Suitable for most use cases, especially when you need a standalone function with its own this.

   • Arrow Function:

     • Well-suited for concise, short functions and when you want to preserve the surrounding this context, such as in callbacks and functional programming.
