Advantages:
Shorter Syntax: Arrow functions provide a concise syntax, making code more readable and reducing boilerplate code, especially for simple one-liner functions.
No this Binding: Arrow functions inherit the ‘this’ value from the surrounding lexical context, eliminating the need to use bind() or store the reference to this in a separate variable.
Implicit Return: Arrow functions with a single expression automatically return the result of that expression, saving developers from writing explicit return statements.
No Binding of arguments: Arrow functions do not bind their own arguments object, which can be beneficial as it avoids potential confusion with other variables named arguments.
Disadvantages:
No arguments Object: As mentioned earlier, arrow functions do not have their own arguments object, which means you cannot access the function arguments using arguments within an arrow function.
No ‘this’ Manipulation: The automatic lexical ‘this’ binding in arrow functions can be disadvantageous in some cases where dynamic ‘this’ manipulation is required.
Not Suitable for Object Methods: Arrow functions are not ideal for defining object methods because they lack their own ‘this’ binding, and using this in such cases would refer to the surrounding context, not the object itself.
Limited Use in Constructors: Arrow functions cannot be used as constructors, which means they cannot be instantiated using the new keyword. This can be a limitation in certain scenarios that require constructor functions.
