Reg is a library and language for pattern matching in ruby data structures. Reg provides Regexp-like match and match-and-replace for all data structures (particularly Arrays, Objects, and Hashes), not just Strings. - coatl/reg
Schema-based validation and coercion for Ruby data structures. Heavily inspired byPrismatic/schema. Meet RSchema RSchema provides a way to describe, validate, and coerce the "shape" of data. First you create a schema: blog_post_schema = RSchema.define_hash {{ title: _String, tags: array(...
Data Structures: Objects and Arrays 相比String, Number, Boolean, Null, Undefined更复杂的数据结构。可以看作是其他数据结构的容器。 一般来说,几乎everything in JS is an Object. 因此, JS可以看成是对象化编程语言。 在浏览器中,一个window加载后,Document对象的一个实例就被创建了。 在这个页面上的所有th...

Chapter 3: Control Structures and Loops 3.1 Conditional Statements Ruby provides several conditional statements, such as "if", "else", and "elsif". These statements allow you to execute different blocks of code based on certain conditions. ```ruby if age >= 18 puts "You are an adult." el...
This chapter will cover topics such as data types, control structures, loops, and functions. Additionally, we will take a closer look at the object-oriented nature of Ruby and how it differs from other programming languages. 1.2 Ruby Gems Ruby Gems are pre-packaged code libraries that extend ...
Control Structures Ruby具有所有常见的控制结构,如if语句和while循环。Java、C和Perl程序员可能会对这些语句的程序体“缺乏花括号”不太适应。Ruby是使用end关键字来表明程序体的结束。 if count > 10 puts "Try again" elsif tries == 3 puts "You lose" else pus "Enter a number" end 同样地,while语句以...
