Code golf is a recreational programming competition where participants compete to create the shortest possible source code that solves a given problem. The name code golf is derived from the similarity of its goal to the game of golf, where players aim for the lowest score (least number of strokes) rather than the highest, as is typical in most sports. Code golfers aim to reduce the number of characters or keystrokes needed to write a program, and several new languages have been created specifically for code golfing, such as GolfScript, Flogscript, Stuck, and Vyxal. Code golf competitions may specify a particular programming language to be used, such as Perl or Python, and can include time limits.

Code Golfing Languages: GolfScript, Flogscript, Stuck, and Vyxal are examples of languages created with code golfing in mind
Code golf is a recreational computer programming competition where participants aim to write the shortest possible code to solve a given problem. The term is derived from the similarity of its goal to that of conventional golf, where players seek the lowest score, the fewest number of strokes to complete a course. Similarly, code golfers strive to reduce the number of characters or keystrokes needed to write a program.
Several new languages have been created specifically for code golfing, including GolfScript, Flogscript, Stuck, and Vyxal. These are Turing-complete languages that facilitate concise expression of ideas. Golfing languages prioritize brevity, often at the cost of readability, which is crucial for practical production environments. Hence, they are often regarded as esoteric.
GolfScript, for instance, can be used to print 1000 digits of pi with a relatively concise code structure. Other golfing languages like 05AB1E, Husk, Pyth, CJam, and Jelly are also popular among code golfers. These languages may be designed for practical purposes but are later found to be suitable for code golf.
Flogscript is another language in this category, designed for code golfing. It emphasizes brevity and creativity in solving programming challenges. Similarly, Stuck and Vyxal are languages constructed with code golfing in mind, offering concise ways to express complex ideas. These languages often sacrifice traditional syntax and structure to achieve extreme conciseness.
Code golf websites and communities actively foster the development of novel golfing languages. These languages are crafted by users to tackle specific code golf challenges, showcasing their ingenuity in problem-solving and language design. The creation of these languages demonstrates the innovative spirit within the code golfing community, constantly pushing the boundaries of what can be achieved with fewer characters and more efficiency.

Code Golfing Competitions: Online and live competitions may include time limits and specific rules
Code golf is a recreational computer programming competition where participants compete to create the shortest possible source code to solve a given problem. The name is derived from the game of golf, where players aim for the lowest score, represented by the fewest strokes, similar to how code golfers strive to reduce the number of characters or keystrokes in their programs.
Code golfing competitions can be held online or in live events, often with time limits to add an extra layer of challenge. These competitions may also have specific rules or constraints to make them more interesting. For example, the International Obfuscated C Code Contest (IOCCC) challenges programmers to write the most obscure and obfuscated C program, avoiding common constructs and tricky statements like "if", "for", and "while". Another example is the js13kGames competition, where game developers are tasked with creating a game using only 13,312 bytes.
The design of code golf competitions often leads to the creation of specific programming language dialects or even entirely new languages. For instance, REBMU is a dialect of REBOL that was created to accommodate the "`open`" nature of some code golf questions. Dedicated golfing languages like GolfScript, Flogscript, Stuck, and Vyxal are designed for extreme brevity, sacrificing readability for conciseness. These languages are often esoteric due to their highly specialized nature.
Online code golf competitions are quite popular and can be found on websites like Code Golf Stack Exchange and code.golf. These platforms provide a space for programming puzzle enthusiasts and code golfers to connect, share knowledge, and participate in various challenges. The competitions often have objective scoring criteria, with points awarded based on the number of characters or keystrokes in the solution.
Live code golfing competitions may also include specific rules and time limits to ensure a fair and engaging contest. These events provide an opportunity for programmers to showcase their skills and creativity in a social setting, fostering a sense of community and friendly competition among participants. The specific rules and time limits can vary depending on the organizer's preferences and the theme of the competition.

Code Golfing Scoring: The score of your solution is the count of Unicode characters in your source code
Code golfing is a recreational programming competition where participants compete to produce the shortest possible source code to solve a particular problem. The term is derived from the game of golf, where players aim for the lowest score (least number of strokes) rather than the highest, as is typical in most sports. Similarly, in code golfing, the goal is to reduce the number of characters or keystrokes needed to write a program.
The scoring system in code golfing is based on the count of Unicode characters in the source code. This means that each Unicode character, regardless of its complexity or byte count in UTF-8, is counted as one. For example, both "A" (U+0041 Latin Capital Letter A) and "😉" (U+1F609 Winking Face) contribute equally to the score, even though the latter has four times the byte count of the former in UTF-8.
In a code golf game with multiple holes, each hole typically has a predetermined point value for the shortest solution, with points decreasing uniformly for longer solutions. The overall score is then calculated as the sum of the points earned on each hole. Additionally, code golf challenges may impose a time limit, such as a maximum execution time of 5 seconds.
The design of code golf languages and dialects reflects the extreme brevity sought by golfers. Languages like GolfScript, Flogscript, Stuck, and Vyxal are Turing-complete languages that facilitate concise expression of ideas. However, their emphasis on brevity often compromises code readability, making them less suitable for practical production environments.
While code golfing may sacrifice readability, it has its practical benefits. For instance, the 2019 use of code golf and Kolmogorov complexity by cryptography researchers Xavier Bonnetain, Léo Perrin, and Shizhu Tian exposed weaknesses in the Streebog and Kuznyechik cryptography algorithms. Their work demonstrated that the algorithms' S-box was significantly less random than claimed.
