Question

I have to use bind() in the method below. I only want to support IE10 and up. Can anyone verify when or if bind() is supported by IE10?

    // Verify console exists
    ...    
    if (window.console) {
        logger = window.console.log.bind(window.console);
        // bind needed for Safari but not FF, possible IE issue?
    } else {
        return false; // window.console not available, silent fail
    }
    ...

bind has been supported in IE since version 9. Take a look at this compatibility table, linked from the MDN docs for bind: http://kangax.github.com/es5-compat-table/
