You will be introduced to the syntax of statement groups, and get an overview of how statement groups can be used for conditional logic as well as for control flow. This is only one small section of a course that takes beginners from simple variables and types all the way through the fundamentals of functions and scope in JavaScript.

My course Introduction to Programming with JavaScript was designed for people who may never have coded, or may have copied and pasted other people’s scripts into a web page without really understanding how they worked. It’s a good general introduction to the concepts of programming in JavaScript, and the features of the language.
