The endsWith()
method determines whether a string ends with the characters of a specified string, returning true

endsWith(searchString)
endsWith(searchString, endPosition)
Parameters
searchString

The characters to be searched for at the end of

searchString
is expected to be found (the index ofsearchString
's last character plus 1). Defaults tostr.length

Return value
true
if the given characters are found at the end of the string, including when searchString
is an empty string; otherwise, false
.
Exceptions
TypeError
-
Thrown if
searchString
is a regex.
