How might the use of immediately-invoked function expressions (IIFE) impact the performance of a JavaScript application?
- IIFE can significantly improve performance by reducing global variable usage.
- IIFE has no impact on performance; it's purely a coding style choice.
- IIFE can slow down performance due to excessive function calls.
- IIFE can lead to memory leaks in JavaScript applications.
The use of IIFE in JavaScript can have a positive impact on performance. By encapsulating code within an IIFE, you reduce the use of global variables, which can lead to fewer naming conflicts and better performance. IIFE is commonly used for encapsulating code safely and efficiently. It's not a performance bottleneck but rather a coding pattern for better code organization.
