Angular

  • Course Code: ANGR
  • Course Dates: Contact us to schedule.
  • Course Category: Angular Duration: 5 Days Audience: Client-side web developers with experience in HTML5 and JavaScript

After understanding how HTML5 and JavaScript work together you soon realize that to create truly capable web applications, the code becomes complex and expensive to maintain. That’s where Angular comes in.  This framework allows us to drastically reduce the amount of JavaScript code written, making our web apps easier to understand at all levels.  Angular lets developers think of their pages as sets of components and makes our web apps truly abstract.

Angular is the framework of choice for organizations who are creating the best and newest web applications.  This fun and interactive course will get your developers ready to begin using Angular to keep you at the cutting edge of technology.

Prerequisites: Understanding of HTML5 and a strong grasp of object-oriented JavaScript.  Please ask about our 5-day JavaScript course which will prepare you for the high-level of JavaScript fluency needed for this course.
