How do you declare a block in Ruby?

A block is made up of code chunks. You give a block a name. In the block, the code is always contained in braces (). A block is always called from a function that has the same name as it. The yield statement is used to start a block.

FAQs

When calling a method in Ruby, all parameters are necessary. You can't define a method that takes a parameter and then call it without one. In addition, if a method is defined to accept only one parameter, it will throw an error if it is called with multiple arguments.
