Clear filtersUI (User Interface)
The means through which a person operates a system, including graphical elements, text, touch or voice. UI is part of user experience; button appearance does not account for all UX.
Definition and sourcesUnit tests
Tests of a small unit of code behaviour. They should detect meaningful regressions; mirroring implementation in assertions can create false confidence.
Definition and sourcesVersion control
Recording file-change history and collaborating on versions. It supports comparison and code recovery but does not replace whole-environment backups.
Definition and sourcesVersioning
Assigning identifiers to releases or changes under a defined policy. SemVer relates numbers to API compatibility, but not every project follows identical rules.
Definition and sourcesVirtual DOM
An in-memory UI representation used to plan real DOM changes. It is an implementation technique, not an automatic performance guarantee.
Definition and sourcesVue.js
A JavaScript framework for declarative component interfaces. It supports different project sizes; complete architecture still needs data and routing decisions.
Definition and sourcesWeb developer
A person developing websites and web applications, specialising in interfaces, server-side work or both. Responsibilities depend on the team and product rather than one compulsory list of languages.
Definition and sourcesWebAssembly
A code format and execution model for compiled modules. It can run inside and outside browsers; permissions depend on the host environment.
Definition and sourcesWebhooks
Notifications sent to an HTTP endpoint after events such as payments. Receivers should verify authenticity and handle retries and duplicates. Webhooks guarantee neither immediate nor exactly-once delivery.
Definition and sourcesWebmaster
A traditional term for someone maintaining a website's operation, updates and publishing. Scope varies by organisation. Larger teams may divide those responsibilities among administrators, developers and editors.
Definition and sourceswebpack
A tool bundling application dependencies and assets. Configuration affects code splitting, caching and output size; bundling does not automatically fix architecture.
Definition and sourcesWordPress
A community-developed open-source content-management system. Themes and plugins adapt the website. WordPress.org is the software project; WordPress.com is a separate hosting service. Free code does not mean cost-free operation.
Definition and sourcesWordPress transient
WordPress temporary-data storage with a maximum lifetime. Values can disappear earlier, so code must be able to regenerate them.
Definition and sourcesYarn
A JavaScript package manager. Installation mechanisms differ between generations; lockfiles and dependency review support reproducible, safer builds.
Definition and sourcesYii Framework
A PHP framework providing application structure and data tools. Yii generations have different requirements and compatibility; the version matters.
Definition and sourcesZend Framework and Laminas
The historical name of a PHP framework and component project continued as Laminas. Older-application migration needs package-name, compatibility and support checks.
