Domain-Specific Language (DSL)

Domain-Specific Language (DSL)

A Domain-Specific Language (DSL) is a computer script that solves software problems in a specific domain. Unlike general-purpose programming languages (GPLs) such as JavaScript or Python, DSLs have a narrower scope and purpose. This specificity allows them to provide concise code and syntax that aligns with a particular domain's programming structure and requirements. 

DSLs allow web developers to build intuitive solutions tailored to a limited set of problems. Popular examples include HTML (Hypertext Markup Language), CSS (Cascading Style Sheets), and SQL (Structured Query Language). The most basic DSLs, often used for a single application, are informally called "mini-languages."

For example, if a website allows you to create graphic designs, using a GLP is challenging and time-consuming, as it requires writing design-related functions in code. 

However, a DSL can let you create specific commands, like createCircle or createSquare, to write succinct code directly aligned with the site's purpose.
