About this course
This course develops practical capability in JavaScript. Its course-specific content covers Language semantics, Data manipulation, Asynchronous execution, Browser integration, followed by an applied project focused on build a browser-based asynchronous data dashboard. The lessons include concrete configuration, design, testing or operational decisions appropriate to the subject.
Who this is for
Administrators, developers and practitioners who work with JavaScript or plan to take on responsibilities in this area.
Before you start
Basic computer literacy and a foundational understanding of programming languages. Prior experience with the named product helps with the practical exercises.
Build a browser-based asynchronous data dashboard
Deliver build a browser-based asynchronous data dashboard. Use the module outcomes to state requirements, demonstrate a working result, test an expected failure or boundary case, and document assumptions and follow-up work.
Course content
Course-specific syllabus and practical exercises. Lab release, access arrangements and final delivery scope are confirmed before enrolment.
