What Happens in JavaScript When You Reassign an Imported Binding
- JavaScript modules handle imports differently than local variables, creating live connections between files.
- ECMAScript Modules (ESM) maintain live references to exported variables, updating values across files.
- Reassigning imported bindings in ESM is prohibited to maintain the module structure.
- Live bindings in ESM dynamically reflect changes in the original source, ensuring synchronization.
- In contrast, CommonJS modules export objects, not live references, resulting in static data imports.
- In CommonJS, reassignment of imported bindings is allowed, impacting the shared object's properties directly.
- However, CommonJS lacks automatic synchronization across files like ESM, requiring manual handling for shared state.
- ESM's structured system enforces read-only imported bindings, highlighting the differences between ESM and CommonJS.
- Understanding how JavaScript manages imported bindings between modules helps prevent unexpected behaviors in code.
- ESM provides a more controlled and synchronized approach to handling modules, while CommonJS offers more flexibility with potential for shared state inconsistencies.

How to iterate over enums in TypeScript (with code examples)
- Enums in TypeScript enable mapping short lists of values into numbers, facilitating comparisons.
- Different approaches for iterating over enums in TypeScript are explored in this article.
- Numeric Enums map keys to numeric values and can be iterated using Object.keys() and Object.entries().
- String Enums map keys to string values and are best iterated using Object.values().
- Object methods like Object.keys() and Object.values() can be used to iterate over enums.
- Iterating over enum values using for loops is another approach, allowing reverse mapping in numeric enums.
- By converting an enum to a typed array, strict typing of enum keys can be preserved for iteration.
- Lodash utility method forIn() can also be used to iterate over enums in TypeScript, providing flexibility in filtering keys.
- A reusable utility function getEnumKeys() is introduced for consistent enum key extraction across codebases.
- Multiple techniques for iterating over enums in TypeScript are discussed, emphasizing the importance of choosing the right method based on requirements.
