The slice() method returns the selected element from an existing array.
Well, I admit I forgot about it!
I'm going to review 1 this time
grammar
arrayObject.slice(start,end)
Array.slice (start, end)
<script type="text/javascript">
var arr = new Array(6)
arr[0] = "George"
arr[1] = "John"
arr[2] = "Thomas"
arr[3] = "James"
arr[4] = "Adrew"
arr[5] = "Martin"
document.write(arr.slice(2,4) + "<br />")
</script>

Select the array indexes 2 through 4
Example code:
Example 1:
The code is as follows:
var a="abcdefgmnlxyz";
console.log(a.slice(2,3));
Intercepts a string from position "2" to position "3", but the character d corresponding to position "3" is not included in the intercept return. Output result :c.
Example 2:
The code is as follows:
var a="abcdefgmnlxyz";
console.log(a.slice(2));
If the second argument is omitted, all characters from position "2" to the end of the string are intercepted. Output result :cdefgmnlxyz.
That's all for this article, I hope you enjoy it.
