Javascript String extend for new function.

Javascript String extend for new function.
First Approch:

String.prototype.toArray=function(){
   let arr=[];
   for(let ch of this){
    arr.push(ch);
	}
	return arr;
}

let name="suresh";
console.log(name.toArray()); //output   [ 's', 'u', 'r', 'e', 's', 'h' ]

Second Approch:

String.prototype.toArray=function(){
	return this.split('');
}

let name="suresh";
console.log(name.toArray()); //output   [ 's', 'u', 'r', 'e', 's', 'h' ]

Difference between functions and methods in JavaScript:

JavaScript Functions:
- A function is a block of code designed to perform a specific task.
- It can be defined using the function keyword, followed by a name and optional parameters.
- The body of the function is enclosed in curly braces.
- Functions are executed when something calls or invokes them.
- Example:
```
function addName(a, b) {
    return a + " " + b;
}
console.log(addName("Suresh", "Sharma")); // Output: Suresh Sharma
```
JavaScript Methods:
- A method is a function associated with an object.
- It is a property of an object that contains a function definition.
- Methods are functions stored as object properties.
- They can be accessed using the following syntax: object.methodName().
- Methods operate on the data contained in a class (i.e., the object it belongs to).
- Example:
```
let employee = {
    empname: "Suresh Sharma",
    department: "Software",
    details: function () {
        return this.empname + " works in "+ this.department +" Department.";    }};
```

console.log(employee.details()); // Output: "Suresh Sharma works in Software Department."

In summary:

A function can stand alone and be called directly by its name.
A method is a function associated with an object property.
Methods implicitly pass the object on which they were called.
