Let's clear some fundamentals.
Hi, devs,
You might be calling any function as a method or a function randomly in your day-to-day software development lifecycle.
So, Let's understand the primary difference between Methods and Functions.
What is a function?
A function is a set of instructions separated from the main code, to call it repetitively wherever needed.
A function can take arguments as inputs to process specific tasks.
A function can have a return value with a specific type to generate output for a particular task.
Functions are part of functional and procedural programming concepts.
What is a method?
A method is also a set of instructions separated from the main code, to call it repetitively wherever needed.
A method can also take arguments.
A method can also have a return value and type.
BUTβ¦.
Here are the key differences between a function and a method.
- Methods are associated with a specific class instance to call it.
- Methods cannot be accessed outside of a class, or they process other data.
- Methods are part of Object-oriented programming concepts.
Basically,
If a function is associated with a class, it's a method. Otherwise, it is simply a function.
Letβs see an example
1. Function
function sum(a,b,c){
return a+b+c;
}
console.log(sum(1,2,3));
2. Method
class Dog{
bark(){
console.log("dog has barked");
}
}
let dog = new Dog();
dog.bark();
and with that,
Thatβs it for this article. I hope I have made you clear.
