Chapter 12 The this Keyword
Conceptual overview of this and how it refers to objects
When a function is created, a keyword called this is created (behind the scenes),
which links to the object in which the function operates. Said another way, this is
available to the scope of its function, yet is a reference to the object of which that
function is a property or method.
Let’s take a look at the cody object from Chapter 1 again:
Sample: sample98.html
var cody = {
living: true,
age: 23,
gender: 'male',
getGender: function () { return cody.gender; }
};
console.log(cody.getGender()); // Logs 'male'.
Notice how inside of the getGender function, we are accessing the gender property
using dot notation (e.g., cody.gender) on the cody object itself. This can be rewritten
using this to access the cody object because this points to the cody object.
Sample: sample99.html
var cody = {
living: true,
age: 23,
gender: 'male',
getGender: function () { return this.gender; }
};
console.log(cody.getGender()); // Logs 'male'.
