javascript toString() method Video explanation

javascript toString() method syntax

How to use the toString() method?

The toString() method can convert a logical value into a string and return the result. The string "true" or "false" is returned according to the original Boolean value or the value of the booleanObject object

Function: Convert the array to a string and return the result.

Syntax: arrayObject.toString()

Return: The string representation of arrayObject. The return value is the same as the string returned by the join() method without parameters.

Note: When an array is used in a string environment, JavaScript will call this method to automatically convert the array into a string. However, in some cases, it is necessary to call this method explicitly.

Note: Elements in the array are separated by commas.
