When deciding to use import * as X from 'X' in JavaScript, it's important to consider the structure and needs of your project. This import syntax is particularly useful in several scenarios:
Namespace Import: When you want to import everything from a module under a single namespace, import * as X from 'X' allows you to do so. This is beneficial when the module exports multiple functions, classes, or variables, and you want to keep them organized under one namespace to avoid naming conflicts with other parts of your code. For example, if a module exports many utility functions, using this syntax can help you reference them clearly in your code (e.g., X.utilFunction()).
Clarity and Maintainability: Using this form of import can make your code more readable and maintainable by explicitly showing that the functions or properties are coming from the module X. This is especially useful in large codebases where tracking the source of imported functions can become complex.
Avoiding Global Namespace Pollution: This method helps in avoiding the pollution of the global namespace. By importing everything as a single object (X), you reduce the risk of name clashes between different parts of your application or with third-party libraries.
Selective Usage: Even though you import everything, you can still use only what you need from the module. This can be clearer than using multiple specific imports if you use many (but not all) exports from a module.
Tooling and Optimization: Modern JavaScript bundlers and tools like Webpack or Rollup can analyze usage of imported modules and can perform tree-shaking to eliminate unused code. Importing as a namespace does not necessarily prevent these optimizations, as unused exports can still be...
