Why are “continue” statements bad in JavaScript? [closed]

Answer 1

Douglas Crockford may feel this way because he doesn't believe in assignment within a conditional. In fact, his program JSlint doesn't even let you do it, even though Javascript does. He would never write:

Example 1

while (rec = getrec())
{   
    if (condition1(rec))
        continue;

    doSomething(rec);
}

but, I'm guessing he would write something like:

Example 2

rec = getrec();

while (rec)
{   
    if (!condition(rec))
        doSomething(rec);

    rec = getrec();
}

Both of these work, but if you accidentally mix these styles you get an infinite loop:

Example 3

rec = getrec();

while (rec)
{   
    if (condition1(rec))
        continue;

    rec = getrec();
}

This could be part of why he doesn't like continues.
