Converting Arrays into CSVs:
Method 1: Using toString() function
The toString() method converts an array into a String and returns the result. The returned string will separate the elements in the array with commas.
Method 2: Using valueof() function
The valueOf() method returns the primitive value of an array. Again the returned string will separate the elements in the array with commas.
There is no difference in toString() and valueOf(). Even if we try with different data types like number, strings etc it would give the same result.
Method 3: using join() function
The join() method joins the elements of an array into a string and returns the string.
By default, the join() method returns a comma (, ) separated value of the array. But you can give an argument to join() method and specify the separator. For example:
Converting CSVs into Arrays: Using split() function
