An alternative method is using the Array constructor.
However, when you want to dynamically create arrays, the array literal syntax may not always be the best method. The most popular method for creating arrays is using the array literal syntax, which is very straightforward. In this article, I share a couple of hacks for creating new JavaScript arrays or cloning already existing ones. Arrays in JavaScript are high-level list-like objects with a length property and integer properties as indexes. However, in ES6, a couple of data types and structures were added to the language, such as symbols, sets, and maps. In JavaScript, there are not so many complex data types - you simply have arrays and objects.
If you have worked with languages like Python or Ruby, you should have seen data types like lists, sets, tuples, hashes, dicts, and so on. Most programming languages provide data types for representing and working with complex data.
