Differences Between Ruby and JavaScript
To fully understand the definitions of Ruby and JavaScript, you can check out this section.
What is Ruby?
Ruby is a high-level programming language that was first released in 1995 by Yukihiro Matsumoto. It is an object-oriented language that is known for its simplicity and flexibility, making it a popular choice for web development, scripting, and system administration. Ruby has a dynamic type system and automatic memory management, which allows developers to write code more quickly and efficiently. It also has a large and active community that has created many libraries and frameworks to make development easier. Ruby on Rails, for example, is a popular web framework that is built on top of Ruby and has been used to create many popular websites and applications.
What is JavaScript?
JavaScript is a high-level programming language that is commonly used to create interactive and dynamic web pages. It was created in 1995 by Brendan Eich, and has since become one of the most popular programming languages in the world. JavaScript is often used in conjunction with HTML and CSS to create web applications, and is supported by all major web browsers. It can be used to add interactivity to web pages, manipulate data, create animations and games, and much more. JavaScript is a versatile language that can be used on both the front-end and back-end of web development, making it an essential skill for any web developer.
