Minifying and Caching Your Site 4 lectures 27:14 Course Overview A basic overview of the topics covered in this course. Caching Your Scripts One of the simplest and yet the most critical things is to cache your code so that it's served in the best way possible to your users.

• Externalize your code
• Always use consistent URLs
• Set ETAGs and expiry rules and use CDN

Creating a Cache Buster The problem with the caching mechanism is that it is complicated to make changes to our code. In this video, we will together create a solution that will work around this problem, making our code robust.

• Using version control for caching
• Changing expiry rules in headers
• Setting no-cache rules

Minifying Your Output For an application to work effectively, it is necessary to send out the smallest possible files. In this video, you will learn how to create a dynamic minifying mechanism to make sure that our code will always be sent in its smallest possible size.

• Condensing the code
• Tools for minifying CSS/JavaScript
• Using server-side configuration

Covering the Foundations 6 lectures 26:52 Always Declare Your Variables Declaring a variable properly is an important step in making your application functional. In this video, you will understand the best ways to declare and define variables.

• Always define your variables
• Avoid using var in the global scope
• Create objects in the local scope

Creating Location References One more important approach towards improving performance of an application is to define it at the right place. In this video, we’ll take a look at the best place and scope to define our variables.

• Create local variables
• Create local references

Condensing var Definitions Condensing var definitions is very helpful in improving the processing speed. In this video, we’ll see how exactly we can do that.

• Condense var definitions
• Define the variable outside if blocks and for loops

Comparing Explicitly When Appropriate Many a times while coding, comparing variables in an exact manner is a very important factor. In this video, we’ll see how to compare variables explicitly.

• Avoid using if statements
• Compare variables explicitly inside the if block

Using String Accumulator-style One of the most common actions with strings is concatenating them. The question is: Is there a better way to concatenate strings? The answer is yes, and you will learn how to do it better in this video.

• Concatenate strings directly using the + operator
• Avoid using functions to concatenate

Building Strings with Arrays At times, you might have too many strings to concatenate. One of the effective ways to do so is by using arrays. We will see why and how it works in this video.

• Creating an array
• Pushing elements into the array
• Joining the elements in a string using the join() method
