Required Blocks

JSLint expects that if and for statements will be made with blocks—that is, with statements enclosed in braces ({}).

JavaScript allows an if to be written like this:

if (condition)
    statement;

That form is known to contribute to mistakes in projects where many programmers are working on the same code. That is why JSLint expects the use of a block:

if (condition) {
    statements;
}

Experience shows that this form is more resilient.
