TL;DR is not a programming task.
Rather, it is an encyclopedic reference.
TL;DR was a programming task. It has been deprecated for reasons that are discussed in its talk page.

"TL;DR" stands for "Too Long; Didn't Read." It's a summary or abbreviation used to provide a brief overview of a longer piece of content, making it easier for readers to quickly grasp the main points without going into details.


Give a brief overview of a programming language. Brief means a hundred words or fewer, preferably fewer.

Focus on the language's key features, design principles, and typical use cases without making direct comparisons or using negative language. Aim to provide an informative and neutral introduction to the language.

APL (A Programming Language) is an array-oriented programming language developed by Kenneth E. Iverson in the 1960s. Its central datatype is the multidimensional array. APL uses a large range of special graphic symbols to represent most functions and operators, leading to very concise code. It has been influential in the development of concept modeling, spreadsheets, functional programming, and computer math packages. APL is known for its powerful and concise syntax, enabling developers to think more about the problem they’re trying to solve than how to express it to a computer. It’s particularly well-suited for working with arrays and matrices, making it an excellent choice for numerical analysis and scientific computing.


Asymptote is a powerful descriptive vector graphics language that provides a natural coordinate-based framework for technical drawing.
