| 6. 31. 1. String.substring() |
|
|
Syntax |
|
string.substring(num1, num2)
string.substring(num)
|
|
The substring() method returns the characters starting with the indexed position num1 and ending with the character before num2. |
The string's first character is in position 0. |
If you pass num1 as a negative number, it will be treated as 0. |
If you pass num2 as a value greater than the string.length property, it will be treated as string.length. |
If num1 equals num2, an empty string is returned. |
It is also possible to pass a single index location to the method. |
