A simple comparison of JSX syntax and template syntax in Vue (analysis of advantages and disadvantages)

In Vue.js, developers can use two different syntaxes to create user interfaces: JSX syntax and Template syntax. Both syntaxes have their own advantages and disadvantages. Let’s discuss their differences, advantages and disadvantages.

JSX syntax and template syntax

JSX syntax is a A syntax extension for JavaScript that allows the use of HTML-like markup languages ​​in JavaScript to define user interfaces. Using JSX syntax, developers can package components and templates in the same file, making the code cleaner and easier to manage.

Template syntax is a syntax similar to HTML and can be used directly in Vue.js. Using template syntax, developers can define the user interface just like writing HTML, making the code more concise and readable. [Related recommendations: vuejs video tutorial, web front-end development]

The difference between JSX syntax and template syntax

• Syntax

  JSX syntax uses an HTML-like markup language to create user interfaces, while template syntax is an HTML-like syntax.

• Data Binding

  JSX syntax supports direct binding to JavaScript variables, while template syntax requires the use of Vue.js instructions to implement data binding.

• Expression

  Expressions in JSX need to be wrapped with a single brace {}, while template syntax uses double braces{{}} to wrap expressions.

• Components

  JSX syntax can define and use components directly in JavaScript, while template syntax requires component definitions and references to be processed separately.

• Slot

  JSX syntax supports passing child elements to components as properties, access them inside the component using this.props.children , and the template syntax is implemented using Vue's slotslot mechanism.

The advantages and disadvantages of JSX syntax and template syntax

The advantages of JSX syntax

• More flexible: Using JSX syntax, developers can more flexibly combine and nest user interfaces, thereby providing users with a richer and more diverse experience.

• Low skill conversion cost: Because JSX syntax and JavaScript are tightly integrated, it is relatively simple for developers who are familiar with JavaScript to learn and use JSX syntax.

• High readability: JSX syntax can make the code closer to HTML, making the code more readable and understandable.

Disadvantages of JSX syntax

• ##High learning curve: Because JSX syntax requires certain JavaScript basics, so the learning curve may be steep for beginners.

• Prone to errors in the writing process: Since JSX syntax requires manual writing of intermediate language code, syntax errors and other problems are prone to occur.

• Not as understandable as template syntax: To use JSX syntax, you must understand some React-specific concepts, such as components, attributes, etc., and these concepts may require some learning cost.

Advantages of template syntax

• Low learning curve: Template syntax can be like HTML Writing user interfaces makes it relatively simple for developers with web development experience to learn and use template syntax.

• Highly readable: Compared with JSX syntax, template syntax is more intuitive and easier to read.

• The writing process is relatively simple: Using template syntax, developers can write code directly in HTML, thus avoiding the problem of manually writing intermediate languages.

Disadvantages of template syntax

• Restrictions: Most editors have restrictions on Vue templates The syntax support is weak

• The reusability is poor, because in Vue, the template is just a view layer and cannot be well combined with the logic code like JSX

Summary

JSX syntax and template syntax each have their own advantages, and the lower limit of using

template syntax is higher , the team's output will not cause subsequent maintenance difficulties due to uneven individual programming levels. The upper limit of JSX syntax is higher, and it can write more elegant code in certain business scenarios.
