{{alias}}( str, search, replacement, fromIndex )
Replaces the substring before the last occurrence of a specified search
string.
If unable to find a search string, the function returns the input string
unchanged.
The function scans an input string from the starting index to the beginning
of the string (i.e., backward).
Parameters
----------
str: string
Input string.
search: string
Search string.
replacement: string
Replacement string.
fromIndex: integer
Starting index (inclusive). If less than zero, the starting index is
resolved relative to the last string character, with the last string
character corresponding to `fromIndex = -1`.
Returns
-------
out: string
Output string.
Examples
--------
> var str = 'beep boop';
> var out = {{alias}}( str, ' ', 'foo', str.length )
'foo boop'
> out = {{alias}}( str, 'o', 'foo', str.length )
'fooop'
> out = {{alias}}( 'Hello World!', 'o', 'foo', 5 )
'fooo World!'
