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 =...
array_name = Array.[](*args) The above is the way we have used it in the last article. In the upcoming articles, you will learn the different ways through which we can declare an Array instance. Well, in this article, we will seehow we can declare an Array object with the help of...
