Javascript iterators is a new concept of ES6 in which it processes each of the items in the collection, which is a pervasive operation. Iterators are a new way to _loop _over any collection in JavaScript.
They were introduced in ES6 and have become popular since they are widely JavaScript provides several ways of iterating over the collection, from simple for loops to map() and filter() Iterators and Generators bring the concept of iteration directly into the core language and provide a mechanism for customizing the behavior of loops.
An iterator is a new concept of ES6. An Iterator is an object that lets us iterate through an Array, an Object, a String, or even custom Objects.
The Iterator allows us to effectively loop over a collection of objects like an array, string, objects, or other data structures.
The most common Iterator in Javascript is the Array iterator, which returns each value in the associated array in sequence.

Today I am going to take a closer look at the new ways we can navigate data structures in the 6th edition of the ECMAScript standard — commonly referred to as ES6. Among all the upgrades and syntactical sugar added to JavaScript in 2015, there is also now support for iterators and iterable objects. These not only allow for less code when iterating over arrays and strings, but support new collections, like maps and sets, and the creation of custom objects and iterators for them. You could think of these as similar to (but not the same as) the looping that happens in a for-in loop on steroids.
Okay, you might be wondering, what even are iterators and iterable objects? An iterable is a sequential data structure that can be iterated over. Iterables can also have their own access method, which defines its iterator. This allows iterables to be publicly accessible. An iteratoris like a pointer that traverses the collection in a particular way. As we will get into in a bit, these new custom iterators in ES6 can loop through more than just a simple array.
This is a lot of jargon that I will break down in a few minutes with an example. But for starters, let’s take a look at the default use of ES6 iterators in the for-of loop.
In ES5 and before, we’re used to seeing for and while loops to iterate over arrays or strings. Now, with ES6, we can hop around an array or a string without having to set the parameters for these loops. The for-of loop by default knows how to iterate over these data types sequentially:

Who invented JavaScript, how it works, as we have given information about Programming language in our previous article ( What is PHP ), but today we will talk about what is JavaScript, why JavaScript is used The Answers to all such questions and much other information about JavaScript, you are going to get here today. Hope this information will work for you.
JavaScript language was invented by Brendan Eich in 1995. JavaScript is inspired by Java Programming Language. The first name of JavaScript was Mocha which was named by Marc Andreessen, Marc Andreessen is the founder of Netscape and in the same year Mocha was renamed LiveScript, and later in December 1995, it was renamed JavaScript which is still in trend.
JavaScript is a client-side scripting language used with HTML (Hypertext Markup Language). JavaScript is an Interpreted / Oriented language called JS in programming language JavaScript code can be run on any normal web browser. To run the code of JavaScript, we have to enable JavaScript of Web Browser. But some web browsers already have JavaScript enabled.
Today almost all websites are using it as web technology, mind is that there is maximum scope in JavaScript in the coming time, so if you want to become a programmer, then you can be very beneficial to learn JavaScript.
In JavaScript, ‘document.write‘ is used to represent a string on a browser.
<script type="text/javascript">
document.write("Hello World!");
</script>
<script type="text/javascript">
//single line comment
/* document.write("Hello"); */
</script>

Symbols, the newest JavaScript primitive, bring a few benefits to the language and are particularly useful when used as object properties. But, what can they do for us that strings cannot?
Before we explore symbols too much let’s first look at some JavaScript features which many developers might not be aware of.
