JavaScript Set entries method example
In this section, we will explore the entries method by examining a range of examples.
Example 1
Let's see a simple example of entries method.
Example
<script>
var set = new Set();
set.add("jQuery");
set.add("AngularJS");
set.add("Bootstrap");
var itr=set.entries();
for(i=0;i<set.size;i++)
{
document.writeln(itr.next().value+"<br>");
}
</script>
Output:
Output
jQuery,jQuery
AngularJS,AngularJS
Bootstrap,Bootstrap
Example 2
Let's see the same example in a different way.
Example
<script>
var set = new Set();
set.add("jQuery");
set.add("AngularJS");
set.add("Bootstrap");
var itr=set.entries();
for(let elements of itr)
{
document.writeln(elements+"<br>");
}
</script>
Output:
