If a directive is accidentally misspelled, it will have no effect.
Recommendation¶
Correct the misspelling.
Example¶
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() { "usestrict"; ... } Correct the misspelling by replacing "usestrict" with "use strict".
