CSE 300 - Software Engineering Home work vs. in class discussion Lectures are 3 hrs per week 7 out of 10 hrs per week is for home work Majority of time is spent in self learning Lectures should be seen as guidance No engineering course will make you learn everything in class. There was plenty of guidance about Associations and instructions were given fro self study. • Class has an improvement opportunity about home work. • • • 3 by Manish Shrotriya

CSE 300 - Software Engineering Javascript asynchronous calling • What do you know about JS functions 8 by Manish Shrotriya

CSE 300 - Software Engineering Javascript asynchronous calling • JS functions ▪ ▪ ▪ ▪ Function declaration vs. function calling vs. function expression JS functions are objects of Function class Functions (except arrow functions) by default have a this object. We can supply which ‘this’ we would like the function to use at runtime. Arrow functions are always called with enclosing this. Functions are also constructors of class with the name same as function name. Function objects by default have prototype property. A prototype is a template of the object. ▪ Properties and methods declared on a prototype are available to every object having that prototype. 9 by Manish Shrotriya
