- [Instructor] One of the key parts of programming is controlling the execution flow of your program. In this chapter we're going to learn about the different kinds of flow control provided by Julia. Now most of this is pretty standard, so if you are already familiar with other languages, then all of this will look very familiar to you. And we're going to start off with conditional statements. These are statements that evaluate a logical expression and then take action based up on the result. So I'm going to open conditionals_start. So one of the most basic of these is the if statement.
