Description

Do you want to improve your coding skills?

The main tool great software developers use is code refactoring. In this course I will introduce you to the concept of this powerful practice.

If you have a beginner or intermediate level knowledge or even if you have great experience writing code this course would be helpful to you.

During this course you will learn the following:

Get familiar with the main types of code smells. Learn to find them in the code

You can optimize your code, make it clearer, more logical and readable

Learn about the most popular refactorings, get acquainted with their mechanics

Learn how to step-by-step apply refactorings in your code

Basic Code Smells

complex expressions and computations

multiple assignments to a temp variable

magic literals in code

hard to understand conditions

nested if statements logic

long method parameter lists

complex method bodies

classes with mixed responsibilities

What is Refactoring

Code refactoring is the process of changing your existing code so that it becomes more readable and easy to modify in future.

But these changes should preserve the existing functionality. Code refactoring is a continuous process and it is done in small incremental steps.

Refactoring Goals

better design

reduced complexity

readability

maintainability

improved architecture

Important to Know

If refactoring is done well, it will greatly improve your code.

by simplifying the underlying logic and eliminating unnecessary levels of complexity.

If done poorly it may change functionality or introduce new bugs.

Refactorings

In this course we will discuss in detail the following refactorings:

Introduce Explaining Variable

Split Temporary Variable

Replace With Constant

Simplify Condition

Split Conditional

Combine Conditional

Replace Conditional With Guard Clause

Introduce Parameter Object

Extract Method

Extract Interface

Extract Class

Extract Super Class
