Intermediate JavaScript Course Overview JavaScript is one of the most popular and commonly used programming languages today. Not only is it the language of the web and front-end frameworks like Angular and React,but it can now be used to build anything (front-end,back-end,or otherwise) thanks to runtimes like NodeJS. This course is designed to move delegates beyond the fundamentals. It serves to set delegates on course to dive into one of the many JavaScript frameworks. Delegates will learn about modern syntax,object-orientation,functional programming,asynchronous programming,managed apps,and testing. Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered. NB: This course assumes ES6 as the baseline specification for JavaScript. This is because ES6 is now widely supported.
TARGET AUDIENCE:
Who will the Course Benefit? The Intermediate JavaScript course is aimed at JavaScript developers who have a handle on the fundamentals and want to take the next step. It may also be of value to those who wish to refresh/renew their knowledge of JavaScript after some time away from it.
COURSE PREREQUISITES:
Requirements Delegates should be able to produce scripts that exploit the fundamental features of the language including variables,functions,conditions and loops,DOM manipulation and event handling. Delegates should also be familiar with HTML and CSS.

COURSE OBJECTIVE:
Course Objectives This course aims to provide delegates with the skills and knowledge necessary to build modern,managed JavaScript applications that exploit modern syntax. Delegates should be able to devise object-oriented and functional solutions to problems,and deal with asynchronous tasks such as IO.
