No matter what framework or 'compiles-to-js' language or library you use, bugs and performance concerns will always be an issue if the underlying quality of your JavaScript is poor. Rewrites, including porting to the framework of the month are terribly expensive and unpredictable. The bugs won't magically go away, and can happily reproduce themselves in a new context. To complicate things further, features will get dropped, at least temporarily. The other popular method of fixing your JS is playing 'JavaScript Jenga', where each developer slowly and carefully takes their best guess at how the out-of-control system can be altered to allow for new features, hoping that this doesn't bring the whole stack of blocks down. This book provides clear guidance on how best to avoid these pathological approaches to writing JavaScript.

If your JavaScript is a mess, frameworks can only do so much to help. No matter what framework, "compiles-to-JS" language, or library you use, bugs and performance concerns will always be an issue if the underlying quality of your JavaScript is poor. With this hands-on guide, youâ??ll learn how test and refactor your existing code to help reduce complexity, improve readability, and gain confidence in the codebase.

Author Evan Burchard shows you how to identify areas of bad code, and then takes you through several refactoring methods for improving them. Techniques range from renaming variables to applying principles of functional and object-oriented programming. If youâ??re motivated to write better JavaScript code either on the frontend or backend, this book is a must. Use refactoring to restructure existing code, without changing its behavior Learn the relationship between refactoring and quality Explore the many versions of JavaScript in use today Create automated tests to confirm that your code works, and find bugs that slip through Learn how to refactor simple JavaScript structures, functions, and objects Refactor your codebase by applying object-oriented and functional programming principles Examine methods for refactoring asynchronous JavaScript

Additional Delivery Information (and some really important bits):

UK Delivery

Orders for delivery in the UK are normally despatched by Royal Mail, using the RM 48 Tracked Service with most orders delivered to you within a few days of placing your order with us. For larger parcels, Courier and Signed For delivery services may be used. Signed Books are shipped in our specially made book mailing cartons, with the books themselves wrapped in paper to protect them. Sometimes we may ship your order in several parts, particularly if you have 'Pre-Order' titles in your order or titles which are held in stock with our publishing partners.

The Really Important Bit: Because we use tracked, courier and signed for delivery services, please use an address at which your parcel can be received during the normal working day, for example, you may want to have your order delivered to your work address if you're not at home during the day.

First Item @ £3.75 (sometimes a shipping supplement may be added for particularly heavy books or specific postcodes*)
2 Items & over @ £5.00 in total

Another Really Important Bit: There are a number of Postcodes in the UK for which we will need to charge a shipping supplement, this will be calculated once we know the size and weight of the shipment. For these orders we will contact customers to agree a suitable and economic method of shipping. There may also be additional time required for delivery to some areas of the United Kingdom. Where possible, we will ship book orders (under 2kg) by Royal Mail to all UK postcodes. Large multiple book orders and books over 2kg are often shipped via APC Overnight or similar, regardless of Postcode.
