A Full Stack Developer should be proficient in various technologies across the stack. This includes:
Security is paramount, so a Full Stack Developer should:
• Implement HTTPS.
• Use secure, hashed passwords.
• Sanitize input to prevent SQL injection and XSS attacks.
• Keep software and dependencies up to date to avoid vulnerabilities.
A RESTful API is an application programming interface that adheres to the principles of REST (Representational State Transfer). It's created by using HTTP requests to access and use data. That data can be used to GET, PUT, POST, and DELETE data types, which refers to the reading, updating, creating, and deleting of operations concerning resources.
Project management involves:
• Using agile methodologies like Scrum or Kanban.
• Breaking down projects into manageable tasks using tools like Jira or Trello.
• Regularly committing code and conducting code reviews.
• Continuous integration and deployment for streamlined workflows.
'State' refers to the storage of user's data or the app's data that's reactive. When the state changes, the UI reflects these changes. In React, for example, state is managed within components using the useState hook, or in more complex applications, using state management libraries like Redux or Context API.
CSS stands for Cascading Style Sheets. It is used to style and layout web pages—for example, to alter the font, color, size, and spacing of your content, split it into multiple columns, or add animations and other decorative features.
In CSS, the box model is a fundamental concept that includes the content, padding, border, and margin of an element. The content is the actual text or images within the element, padding is the space between the content and the border, the border surrounds the content and padding, and the margin is the outermost layer that separates the element from other elements.
To make a website responsive, you can use CSS media queries to apply different styles depending on the screen size, resolution, or device orientation. Additionally, flexible grid layouts, flexible images, and an understanding of relative units like percentages or viewport units are crucial.
A closure is a feature in JavaScript where an inner function has access to the outer (enclosing) function's variables—a scope chain. The closure has three scope chains: it has access to its own scope (variables defined between its curly brackets), the outer function's variables, and the global variables.
The == operator tests for abstract equality and will perform type conversions if the values are not of the same type before comparing. The === operator tests for strict equality and will return false if the values are not of the same type.
Asynchronous operations can be handled using callbacks, promises, or async/await. Callbacks are functions passed as arguments to be executed after the asynchronous operation. Promises represent the eventual completion (or failure) of an asynchronous operation and its resulting value. Async/await is syntactic sugar built on top of promises that allows writing asynchronous code in a synchronous manner.
