How to Become a Software Engineer: A Step-by-Step Path
A step-by-step software engineering roadmap with skills, milestones and realistic timelines, plus how to land your first developer role with or without a degree.
JavaScript Object Notation: a lightweight, text-based format for storing and exchanging structured data.
JSON represents data as key-value pairs and ordered lists using a simple, human-readable syntax. Keys are quoted strings, and values can be strings, numbers, booleans, null, arrays in square brackets, or nested objects in curly braces.
Although it originated from JavaScript, JSON is language-independent, and almost every programming language can read and write it. It has become the default format for web APIs, configuration files, and many NoSQL databases. For example, this glossary itself could be stored as a JSON array of term objects, each with fields for the term, a short definition, and related entries. JSON does not support comments, which is one reason some configuration tools prefer YAML instead.
Application Programming Interface: a defined set of rules that lets one piece of software request data or services from another.
JSON Web TokenA compact, signed token format used to securely pass identity and permission claims between a client and a server.
NoSQLA broad category of databases that store data in formats other than traditional relational tables, such as documents, key-value pairs, or graphs.
REST APIAn API that follows Representational State Transfer principles, using standard HTTP methods and URLs to work with resources.
Schema MarkupStructured data code added to web pages that tells search engines exactly what the content is, such as a product, recipe, event, or business.
XMLExtensible Markup Language: a text-based format that uses custom tags to structure, store, and exchange data.
YAMLA human-readable data format that uses indentation to represent structure, widely used for configuration files.
