A map polyfill in JavaScript provides functionality for environments that do not support the native Array.prototype.map method. It replicates the behavior of the map method, allowing you to apply a provided function to each element in an array, creating a new array with the results. The polyfill ensures compatibility across older browsers by adding the map method if it doesn't exist.
