Today's JavaScript lesson is, Learn How The this Keyword Works in JavaScript, Advanced Objects on Codecademy, Learn JavaScript. The lesson is, "The This Keyword". In it we learn how to call other properties within methods we write within our object. If we have a method within our object and we want to call another properties value, you cannot do so using the key name. Since we are not able to use the keys name to access the objects property value, we must instead use the this keyword. Learning to use the this keyword in JavaScript will help you advance your JavaScript path. Being able to access object properties through the use of the this keyword is a common occurance for many JavaScript developers. Learn how to become an expert javascript developer, but first you must learn how to be a JavaScript developer! Then you may advance. Just make sure to remember that the this keyword references the calling object. This gives us access to the calling object's properties! Practice using the this keyword with JavaScript objects to truly begin to master the JavaScript programming language!
