JavaScript is a powerful language. On the web, it is your only real choice to build a true portable application that works on any browser, any device and any operating system. However, there are some drawbacks! JavaScript does have some very bad features that should not be used. Too often, the language is dismissed because of these bad parts. Many developers have made the mistake of underestimating the language, due to its superficial similarity to mainstream languages such as Java or C#. However, when you see past this, what remains is a very beautiful and exceptionally powerful language. Using Crockford’s “JavaScript: The Good Parts”, this course will teach developers with some existing JavaScript experience what parts to avoid, and what parts to embrace. This will be accompanied by an experienced trainer, helping in-person to really understand the cryptical analysis of the book. This will help tremendously in writing JavaScript applications that use the language to its full potential.
