substring

Returns a string that is a substring of another string. The substring begins with the character at the specified index (counting from 0) and extends to the character at the end index -1. If the end index is entered as -1, the substring ends as the last character in the input string.

Syntax

string = substring(str, beginIndex, endIndex)

Example

print substring("The end is nigh", 4, 7)

end
```js
print substring("The end is nigh", 8, -1)

is nigh
