Esaiest way to Check if a Javascript variable's value is between several ranges?

If a number should be tested against a few ranges of values, this works :

if ((number > a && number < b)||(number > b && number < d))
    {return true;}
    else {return false;}

This is handy for just 2 ranges, but it is not very convenient if there are lots of ranges of values.

Any other option here ?
