Fold, often referred to as reduce in JavaScript, allows developers to apply a function to an array, simplifying data processing and enhancing readability.
Fold is a higher-order function that applies an accumulator function to all items in an array, producing a single cumulative result.
Implementing fold with Array.prototype.reduce transforms traditional loops into concise expressions, improving both readability and maintainability of the code.
The versatility of fold makes it useful for various data processing tasks, like summing, multiplying, and counting occurrences.
