JavaScript Array entries() Example Create an Array Iterator, and then iterate over the key/value pairs: constfruits = ["Banana","Orange","Apple","Mango"]; constf = fruits.entries(); for(letx of f) { document.get
Every Array has a function which you can use to create an iterator. This function can only be accessed by using theSymbol.iteratoras a key on the Array. Once you have created your iterator, you can use it to iterate through each value of the Array using.nextor afor loop. constabcs =...
