getters and setters javascript

Comment

// although you can just grab a property directly like this 
Car1.colour
// or modify it like this
Car1.colour = "red"

// on the other hand, getter methods look like this
get colour() { // doesn't need a parameter
  return this.colour // optionally attach values or operations on to it
}
// and setter methods look like this
set colour(newColour) {
 this.colour = newColour 
}
//Benifits of getters and setters

// implement logic that uses private data in the class
// eg. I might want to blend it with the current car colour

// Encapsulation: allows you to control how the data is accessed or modified.
// especially if you are implementing other logic

// Readability: code is much clearer as it is now in a method

// Compatibility: Some APIs or libraries expect you to use getters/setters

Getters and Setters

Comment

Get and set

In order to allow controlled access to properties from outside the class, getter and setter methods are used.

A getter method allows reading a property’s value.

A setter method allows modifying a property’s value.

It is a common convention to write the name of the corresponding member fields with the get or set command.

Example

Let’s write get and set methods for __username in our User class.

class User:
    def __init__(self, username=None):  # defining initializer
        self.__username = username

    def setUsername(self, x):
        self.__username = x

    def getUsername(self):
        return (self.__username)


Steve = User('steve1')
print('Before setting:', Steve.getUsername())
Steve.setUsername('steve2')
print('After setting:', Steve.getUsername())

js why to use getters and setters

Comment

1) Syntax reasons. It’s easier and faster to read code 
created with accessor functions
2) Encapsulation. I can create safer code with accessor functions.
