Ed has also developed a new suite of PHP courses and has extensive experience with HTML/CSS and MySQL.Įd is responsible for delivering QA’s Programming Foundations course using the Eclipse IDE. Ed mainly delivers courses in JavaScript covering vanilla JS, ES2015+, TypeScript, Angular, and React (the latter is authored by Ed) and has delivered on behalf of Google for PWAs. Ed describes himself as practically minded, a quick learner, and a problem solver who pays great attention to detail.Įd’s specialist area is training in Emerging Technologies, within Web Development. Ed continues to develop existing and new courses, primarily in web design using: PHP, JavaScript, HTML, CSS, SQL, and OOP (Java), Programming Foundations (Python), and DevOps (Git, CI/CD, etc). Previous roles have included being a Delivery Manager, Trainer, ICT teacher, and Head of Department.

More on that in other videos.Įd is an Outstanding Trainer in Software Development, with a passion for technology and its uses and holding more than 10 years’ experience. Instead, we'll use ternary expressions and looping functions like forEach where needed. Something to remember in the future, we can't use 'if' or 'for' loops inside JSX expressions as it needs to be a valuable. We can also use JSX as expressions in 'if' statements and 'for' loops, as an argument in expressions and function calls, and there can even be return from functions as the example show here does.

In some code editors such as VS Code, the empty angle brackets are acceptable shorthand for the React fragment component.

The example shown here would render 'Welcome to My React App' to the screen. This means that we can assign JSX expressions to variables and embed regular JavaScript expressions inside the JSX using curly braces. After compilation, JSX expressions become regular JavaScript function calls that evaluate the JavaScript objects. JSX can be used as an expression in component code. But more importantly, miss out on error and warning messages that the React library will produce as part of the conversion process. You don't have to use JSX to write React code, but writing Vanilla JavaScript means you will lose its readability. The main job of the JSX, as files were concerned, is to take the HTML code shown here and re-box it into React's create element function with the relevant augments as shown below. It does this by escaping values embedded in JSX and converting them to a string before rendering them. Under the hood, the transpilation and optimization processes are more efficient when working with JSX, and it helps to prevent cross-site scripting attacks. This makes the component code easier for developers to understand and quick to follow and to write. It cleans up the mixture of HTML and JavaScript that is needed to create our React component. It stands for JavaScript Syntax Expression and Facebook recommend using it because it provides syntactic sugar over our component code. JSX was developed by Facebook to help write cleaner React code.
