Wat is Git?
Snelle definitie
Git is een gedistribueerd versiebeheersysteem dat wijzigingen in broncode bijhoudt tijdens softwareontwikkeling, waardoor samenwerking tussen meerdere ontwikkelaars mogelijk is.
Git is the most widely used version control system in the world. Created by Linus Torvalds in 2005 (the same person who created Linux), it tracks every change made to every file in a project, who made the change, and when. This creates a complete history that can be navigated, compared, and reverted at any point.
The key concepts in Git include repositories (the project folder with its history), commits (snapshots of changes), branches (parallel versions of the code), and merges (combining branches). Developers typically work on feature branches, make commits as they progress, and merge their changes back to the main branch when complete.
GitHub, GitLab, and Bitbucket are platforms that host Git repositories remotely and add collaboration features — pull requests (code review before merging), issues (bug tracking), CI/CD pipelines (automated testing and deployment), and access controls.
Git's distributed nature means every developer has a complete copy of the project history on their machine. This enables offline work, fast operations, and natural backup — if a server goes down, any developer's copy can restore the entire project.
Waarom het belangrijk is
Without version control, software development is like editing a document without undo. One mistake can destroy hours of work, and coordinating changes between team members becomes chaos. Git makes collaboration safe and traceable.
For businesses, Git provides an audit trail of every code change, enables safe experimentation through branches, and makes it possible to quickly revert problematic changes in production.
Praktijkvoorbeelden
A team of 50 developers works on the same codebase using Git branches — each developer works independently without affecting others, merging changes through reviewed pull requests
A production bug was traced back to a specific commit using 'git bisect', identifying exactly which change caused the issue and who made it
A startup's entire production history is stored in Git, allowing them to see the state of their application at any point in time over 3 years of development
An agency uses Git branches to maintain separate client customizations of a shared template, merging core improvements to all clients simultaneously

Version Control
Versiebeheer is een systeem dat wijzigingen aan bestanden in de loop der tijd registreert, waardoor ontwikkelaars de geschiedenis kunnen bijhouden en naar eerdere versies kunnen terugkeren.
CI/CD (Continuous Integration / Continuous Deployment)
CI/CD is een reeks praktijken die het testen, bouwen en deployen van code automatiseren, zodat ontwikkelteams snel en betrouwbaar kunnen leveren.
TypeScript
TypeScript is een programmeertaal die JavaScript uitbreidt door statische typen toe te voegen, waardoor fouten vroeg in het ontwikkelingsproces kunnen worden gedetecteerd.
API (Application Programming Interface)
Een API is een set regels en protocollen waarmee verschillende softwaretoepassingen met elkaar kunnen communiceren, gegevensuitwisseling en het delen van functionaliteiten mogelijk maakt.
