JWT

JWT (JSON Web Token) is an open standard (RFC 7519) for securely transmitting information between parties as a JSON object. It is commonly used for authentication and authorization in web applications, allowing stateless verification of user identity through digitally signed or encrypted tokens. JWTs consist of three parts: a header, a payload, and a signature, which together ensure data integrity and authenticity.

Also known as: JSON Web Token, JWT Token, JWT Auth, JWT Authentication, JsonWebToken

🧊Why learn JWT?

Developers should learn JWT when building modern web applications that require secure, stateless authentication, such as single sign-on (SSO) systems, API security, and microservices architectures. It is particularly useful for scenarios where server-side session storage is impractical, as JWTs can be verified without database lookups, reducing server load and improving scalability. However, it's important to implement proper security measures, such as using HTTPS and storing tokens securely, to prevent vulnerabilities like token theft.

2D animation is the process of creating movement in a two-dimensional artistic space, typically involving sequential images or frames to simulate motion. It is widely used in video games, films, television, web content, and mobile applications to bring characters, objects, and environments to life. Techniques range from traditional hand-drawn animation to modern digital tools that streamline the creation process.

2D graphics is a field of computer graphics focused on creating and manipulating two-dimensional visual content, such as images, shapes, text, and animations, using mathematical representations like vectors or pixel-based raster formats. It involves techniques for rendering, transforming, and compositing 2D elements on digital displays, often used in applications like user interfaces, games, data visualization, and digital art. This concept underpins many libraries, frameworks, and tools that developers use to build visual components in software.

2D Image Processing

2D Image Processing is a field of computer science and engineering focused on analyzing, manipulating, and enhancing digital images using algorithms and computational techniques. It involves operations on two-dimensional arrays of pixel data to extract information, improve visual quality, or transform images for various applications. Common tasks include filtering, segmentation, feature detection, and compression.

3D Graphics is a field of computer science and digital art focused on creating, manipulating, and rendering three-dimensional visual content using mathematical models and algorithms. It involves techniques for modeling objects, applying textures and lighting, and simulating realistic or stylized scenes in applications like video games, films, simulations, and virtual reality. The process typically includes stages such as modeling, rigging, animation, and rendering to produce 2D images or interactive experiences from 3D data.

3D Image Processing

3D Image Processing is a field of computer vision and medical imaging that involves analyzing, manipulating, and interpreting volumetric data, such as CT scans, MRI images, or 3D models. It focuses on techniques for segmentation, registration, reconstruction, and visualization of three-dimensional datasets. This enables applications like disease diagnosis, surgical planning, and 3D modeling in industries such as healthcare, engineering, and entertainment.

3D models are digital representations of three-dimensional objects created using specialized software, consisting of vertices, edges, and faces to define shapes and surfaces. They are widely used in industries such as gaming, animation, virtual reality, architecture, and product design for visualization, simulation, and interactive applications. These models can be textured, rigged for animation, and exported in various file formats for use across different platforms and engines.
