javascript - how to get the last character of a string? -

-

how last character of string:

"linto.yahoo.com."

the last character of string "."

how can find this?

an elegant , short alternative, string.prototype.slice method.

just by:

str.slice(-1);

a negative start index slices string length+index, length, being index -1, last character extracted:

"abc".slice(-1); // "c";
