The ToString () method in JS

Today read the JS learning materials, see a ToString () method, in JS, all defined objects have the ToString () method.

The ToString () method of the number type is special, with both the default mode and the base mode.

Example of default mode:

var num1 = 10;

var num2 = 10.0;

Alert (num1.tostring ());//Output 10

Alert (num2.tostring ());//Output 10

No matter what notation you use to declare numbers, the default mode is only returned in decimal.

Example of a base pattern:

var num1 = 10;

Alert (num1.tostring (2));//Output 1010

Alert (num1.tostring (8));//Output 12

Alert (num1.tostring (16));//Output A

It is obvious that the base mode is to convert the numerical type into the corresponding binary.
