Incrementing Vars Preferred Method?

[RMWChaos]

Yet another inane question...but I am looking for coding "best practices" here.

I have always used i++ to increment vars, but have recently found that some well-respected JS coders such as Douglas Crawford use a different method i += 1.

When incrementing by a single integer (1), is the += method still preferred? I can see if you wanted to increment by a value greater than 1 (i.e. i += 2, 3, ... infinity), but otherwise, what is the benefit? Are there situations where i++ can fail or cause problems?

Thanks.

(function(){
    var i= 0,j= 0, tem;
    var A= [],B= [];
    while(i<10){
        A[i]= i+= 1;
        B[j]= j++;
    }
    alert('i+=1 returns: '+A+'\ni++ returns: '+ B);
})()

Oh, brilliant!

Thanks!
