I'm just wondering what it means to attach a number as a parameter to the toString() method

E.g. obj.toString(10);

I googled and i have never seen a parameter before.

The additional parameter works only for Number.prototype.toString to specify the radix (integer between 2 and 36 specifying the base to use for representing numeric values):

var number = 12345;

number.toString(2) === 11000000111001

number.toString(3) === 121221020

// …

number.toString(36) === 9ix
