JavaScript join() Method
The join function is a javascript inbuilt function that is used to join the array of elements and return it as a string. This method has only one optional parameter.
array.join(separator)
Example 2: Here we use method chaining to use both the methods together at a time.
<script>
let string = "w3wiki";
/* split method split the string into an
array(['Geeks','Geeks']) and the join method will
join the string with another string ('and') */
let replaced_string = string.split("For").join("and");
console.log("The replaced string is " + replaced_string);
console.log("The original string is " + string);
</script>
Output:
The replaced string is GeeksandGeeks
The original string is w3wiki
