How does lodash.forEach work?
lodash.forEach
is a utility function in the Lodash library that provides an easy way to iterate over elements of an array, collection, or object and perform a given operation on each of them without creating a new array or object. It takes three parameters - the collection to iterate over, the function to call on each iteration, and the context object to use as the this
value for the function.
