If a directive is accidentally misspelled, it will have no effect.


Correct the misspelling.


The following code snippet shows a function that contains a "usestrict" directive. Most likely, the programmer intended this to be a "use strict" directive, but due to the typo, the function will not execute in strict mode.

function f() {

Correct the misspelling by replacing "usestrict" with "use strict".
