for inside class js code example
Example 1: es6 class example
<script>
class Student {
constructor(rno,fname,lname){
this.rno = rno
this.fname = fname
this.lname = lname
console.log('inside constructor')
}
set rollno(newRollno){
console.log("inside setter")
this.rno = newRollno
}
}
let s1 = new Student(101,'Sachin','Tendulkar')
console.log(s1)
//setter is called
s1.rollno = 201
console.log(s1)
</script>
Example 2: javascript classes
//use classes by initiating one like so:
class MyClass {
constructor(FirstProperty, SecondProperty, etcetera) {
//The constructor function is called with the new class
//instance's parameters, so this will be called like so:
//var classExample = new MyClass("FirstProperty's Value", ...)
this.firstProperty = FirstProperty;
this.secondProperty = SecondProperty;
}
//creat methods just like functions:
method(Parameters) {
//Code Here
}
//getters are properties that are calculated when called, versus fixed
//variables, but still have no parenthesis when used
get getBothValues()
{
return [firstProperty, secondProperty];
}
}
//Note: this is all syntax sugar reducing the boilerplate versus a
// function-defined object.
