With Maps, we can have key-value pairs where the keys aren’t strings. Maps are collections that can be iterated in the order that the key-value pairs are inserted in. They can be converted to arrays with each entry being an array with the key as the first element and the value as the second element, which means that we can convert them to arrays and then use arras operations like array methods.
Previous: Write a JavaScript program to create an array of key-value pair arrays from an given object. Next: Write a JavaScript program to get a customized coalesce function that returns the first argument that returns true from the provided argument validation function.

The above snippet stores a hash in Redis that maps each technology to its framework. The first argument to hmset() is the name of the key. Subsequent arguments represent key-value pairs. Similarly, hgetall() is used to retrieve the value of the key. If the key is found, the second argument to the callback will contain the value which is an object.
