1.确保这个值等于ture

if (someBoolean == true) {
    doSomething();
}

2.只有等于ture时我才return ture

if (result == true)
    return true;
else
    return result;

3.我就是不信任if

if (result <= 10) {
    handling();
}
else if (result > 10) {
    otherHandling();
}
else {
    handling(); // to be sure
}

4.要写出一看就懂的代码

function DocumentDotWrite(s){
    document.write(s);
}
