A block is the same thing as a method, but it does not belong to an object. Blocks are called closures in other programming languages. There are some important points about Blocks in crystal: Block can accept arguments and returns a value. ...
The initialize method is useful when we want to initialize some class variables at the time of object creation. The initialize method is part of the object-creation process in Crystal and it allows us to set the initial values for an object. Below ar...
A regular expression is a sequence of characters that define a search pattern, mainly for use in pattern matching with strings. Ruby regular expressions i.e. Crysal regex for short, helps us to find particular patterns inside a string. Two uses of Cr...
The word iterate means doing one thing multiple times and that is what iterators do. Sometimes iterators are termed as the custom loops. “Iterators” is the object-oriented concept in crystal. In more simple words, iterators are the methods w...
In crystal lang, static members are known as class variables. These variables are shared among all instances of a class and are declared using the @@ symbol. Class variables retain their value across different instances of the class and can be access...
crystal is the ideal object-oriented language. In an object-oriented programming language, inheritance is one of the most important features. Inheritance allows the programmer to inherit the characteristics of one class into another class. crystal su...
