First off, a programming language is a language that computers can understand. You can think of them as a specific set of instructions that computers can follow. Often, we try to pick the best language for the job when beginning a project. And we usually take it a step further with picking the best tools in that language for the job. In web development, we always have HTML, CSS, and JavaScript. Often, it’s complicated to write websites in purely these three, so we use a different language that generates the HTML, CSS, and JavaScript for us.
HTML is the main code of the web. It is the markup language that provides the skeleton to all websites.
CSS is the design of the web. It is a language that gives elements their color, width, shadows, and more.
JavaScript (or JS) is the language of the web, it’s the main language in which browsers like Chrome can run code for sites.
TypeScript (or TS) is a superset of JavaScript that introduces types in to the language. Types help catch bugs and speed up development.
JSDoc is a recent alternative to TypeScript that allows for annotations to be added to JavaScript code, to give type inference. It isn’t technically a language as it is just used on top of JavaScript.
