The toString() method returns a string formed by the elements of the given array.
Example
toString() Syntax
The syntax of the toString() method is:
arr.toString()
Here, arr is an array.
toString() Parameters
The toString() method does not take any parameters.
toString() Return Value
- Returns a string representing the values of the array separated by a comma
Notes:
- The
toString()method does not change the original array. - Elements like
undefined,null, or empty array, have an empty string representation.
Example 1: Using toString() Method
Output
Terence,28,Kathmandu [ 'Terence', 28, 'Kathmandu' ]
In the above example, we have used the toString() method to convert all the elements of the info array into a string.
info.toString() returns the string representation of info which is Terence,28,Kathmandu.
Since the method does not change the original array, the info array holds the same original value.
Example 2: toString() with Nested Arrays
When we use the toString() method in a nested array, the array is flattened. For example:
Output
1,2,4,Apple,5
