The goal is the shortest source code to solve a problem
Code golf is a recreational computer programming competition where participants compete to write the shortest possible source code to solve a particular problem. The name is derived from the similarity of its goal to that of the game of golf, where participants aim for the lowest score, as opposed to most sports where a higher score is better. In code golf, the aim is to reduce the number of characters or keystrokes, akin to golfers minimising the number of club strokes to complete a course.
The concept of code golf is not new, with a 1962 coding manual noting the challenge of coding with the fewest instructions. However, the term "code golf" was first used in 1999 with Perl, and later gained popularity through the use of Perl for RSA encryption. Today, code golf covers a wide range of programming languages, and there are even dedicated golfing languages like GolfScript, Flogscript, Stuck, and Vyxal. These languages are designed for extreme brevity, sacrificing readability, which is often valued in practical production environments.
Code golf challenges can be found on websites like code-golf.io, offering problems of varying difficulty levels and programming languages. For instance, a challenge may involve printing the first 1000 digits of pi or creating a demo in 1024 characters of JavaScript. While code golf can be enjoyable and stimulating, some caution against its application in professional settings, arguing that shorter code does not always equate to better code. Readability and scalability are crucial considerations in programming, and code golf solutions may compromise these aspects, making it challenging for developers to understand and maintain the code.
Despite the potential drawbacks, code golf can be a fun way to showcase one's programming skills and creativity. It encourages participants to think outside the box and express ideas concisely, often leading to innovative solutions. Whether as a recreational activity or a friendly competition among programmers, code golf offers a unique perspective on the art of writing efficient and concise code.

Code golfers sacrifice readability for brevity
Code golf is a recreational computer programming competition in which participants compete to write the shortest possible source code to solve a given problem. The name is derived from the similarity of its goal to that of the game of golf, where participants seek the lowest score, or in this case, the fewest number of characters.
The nature of code golf means that the design of golfing languages often sacrifices readability for extreme brevity. This can make the code difficult to understand, especially for those new to the project or language. For example, a code golf participant might write 'l,r' instead of 'left, right', or they might assign a variable, compare something, and return a value all in the same line, making the code less readable.
In a programming language like Python, for instance, the goal is for the code to be readable and to resemble English as much as possible. However, code golf participants may favour shorter variable names or use abbreviations, which can make the code harder to understand, even for the original author if they revisit the code after a long period.
Code golf can be a fun challenge, but it can become a problem when it is applied in professional settings. Well-written code should be a balance of readability and performance, and code golf tends to prioritise brevity over other important factors. Therefore, while code golf may be an interesting way to develop one's programming skills, it is important to remember that sacrificing readability for brevity may not always be the best approach, especially in collaborative or production environments.

The term comes from golf's lowest-score-wins rule
Code golf is a recreational computer programming competition in which participants aim to achieve the shortest possible source code to solve a particular problem. The name "code golf" is derived from the scoring system of traditional golf, where the objective is to complete the course in the fewest strokes possible. Similarly, in code golf, the goal is to write a program that solves a given problem using the fewest characters or keystrokes. This competition is not about achieving the highest score, but rather the lowest, which is a unique feature compared to most sports and game scoring systems.
The concept of code golf is not new, with similar informal competitions known to have been popular with early APL hackers. The challenging nature of optimising code for size has long been recognised, as evidenced by a 1962 coding manual that cautioned against the time-consuming nature of coding with the fewest possible instructions. Today, code golf has evolved to cover a wide range of programming languages, including dedicated golfing languages such as GolfScript, Flogscript, Stuck, and Vyxal. These languages are designed with extreme brevity in mind, sacrificing readability for conciseness.
The goal of code golf is to find the most efficient and concise solution to a problem within the constraints of a specific programming language. This can lead to creative and elegant code that pushes the boundaries of what can be achieved with minimal instructions. However, it's important to distinguish between code golf and practical programming. In real-world settings, writing code that is readable and scalable takes precedence over brevity. Longer, more explicit code can be easier to understand and maintain, especially when collaborating with a team or returning to a project after a long break.
While code golf may seem like a niche activity, it has gained popularity among programmers who enjoy the challenge of optimising their code. It provides an opportunity to showcase one's programming skills and creativity while also contributing to the development of new programming languages and dialects specifically designed for code golfing. Websites like code-golf.io offer challenges for various programming languages, attracting enthusiasts from different communities.
The term "code golf" reflects the competition's nature, drawing an analogy between the quest for the lowest score in golf and the pursuit of the fewest characters in programming. This terminology adds a playful element to the activity, inviting programmers to test their skills in a unique and engaging way.
