Arrow functions and regular functions are both ways to define functions in JavaScript, but they have some key differences in terms of syntax, behavior, and usage. Here are the main differences between them:
Regular function gets hoisting at top. This means that you can call a regular function before it's actually defined in the code, and JavaScript will hoist the function declaration to ensure that the function call works correctly.
Arrow functions are not hoisted like regular functions, and you must define them before you can use them in your code.
You can write Regular function and Arrow function in this way,
In regular functions, the arguments object can be used to access the arguments that were passed to the function when it was called.
Arrow functions do not have their own arguments binding. The arguments object is not available in arrow functions.
In regular functions , duplicate named parameters are allowed.
Arrow functions not allowed the duplicate parameters.
Regular functions have their own this context, which is determined by how they are called (this can be explicitly set using bind, call, or apply).
Arrow functions do not have their own this context. Instead, they inherit the this value from the surrounding lexical context (the enclosing function or global scope).
Regular functions can be used as constructors to create new objects when called with the new keyword.
Arrow functions cannot be used as constructors to create objects with the new keyword. Attempting to do so will result in a runtime error.
Regular functions are more versatile and can be used in various scenarios, including as methods in objects, event handlers, constructors, or standalone functions.
Arrow functions are often used for short, concise functions, especially when you need to preserve the lexical scope of this.
