One way I really like to write Ruby is to use an if statement after the code to be executed: def hey_ho? ![]() This else statement will be executed when the if expression is false: if 1 > 2ġ is not greater than 2, so the code inside the else statement will be executed. For example: if trueĢ is greater than 1, so the puts code is executed. If something is true, it executes what’s inside the statement. # booleansīook_price = 15.80 Conditional Statements: Control FlowĬonditional statements evaluate true or false. In the example above, a two variable stores an integer of 2 and some_number stores 10,000.īesides integers, we can also use booleans (true/false), strings, symbols, float, and other data types. You can assign a value to whatever variable you want. How simple was that? You just assigned the value 1 to a variable called one. Imagine you want to store the number 1 in a variable called one. In Ruby it’s easy to define a variable and set a value to it. You can think about a variable as a word that stores a value. Let’s get started with some basics! Variables ![]() It has an elegant syntax that is natural to read and easy to write.”. Ruby is “A dynamic, open source programming language with a focus on simplicity and productivity. The second - and main - reason is Rails: the same framework that Twitter, Basecamp, Airbnb, Github, and so many companies use. It’s natural to code and it always expresses my thoughts. “Ruby is simple in appearance, but is very complex inside, just like our human body.” - Matz, creator of the Ruby programming languageįor me, the first reason is that it’s a beautiful language.
