The String.prototype.split() function divide the string into array of sub-strings. You can perform other array manipulation on the resultant string.
The syntax for split() function is given below.
String.split([separator, limit]);Separator – it is a character that is used to separate the sub-strings. It is optional, however, a separator is required to divide the sub-strings.
Limit – it is the number of characters to be split. This is also optional.
Examples: split() function
Here are few examples of split function with and without separators.
var Str = "Hello World";
Str.split('');
// result in single character split
//Output - "H","e","l","l","o", " ","W", "o", "r","l","d"
Str.split(' ');
//result in split between works rather than single characters
//Output - "Hello", "World"
Str.split();
//No arguments, the whole array is returned
//Output - Array["Hello World"]
Str.split('', 4);
//Limit set to 4, therefore, split only four letters
//Output - "H","e","l","l" Example Program: split() function
