Question

I’ve got a javascript file (.js) that I’m editing in Eclipse (Juno). It’s giving me this warning:

Type mismatch: cannot convert from Number to ___anonymous6554_6555

on the return line of this code (this is a simplified example, but it still shows the error):

function foo() {
    var temp = {};
    if (true) {
        temp = 1;
    }
    return temp;
}

If I change it to:

function foo() {
    var temp = new Object();
    if (true) {
        temp = 1;
    }
    return temp;
}

the warning goes away, but then jsHint warns me to use object literal notation. Grrr…

Any ideas where that might be coming from? The warning looks like a java warning to me….

EDIT

This is Eclipse’s fault. Take a look at this similar question: Why does Eclipse sometimes warn about arrays of arrays in JavaScript?

I’d ignore the warning (the Java warning), and use {}.
