Help with JS and functions parameters

Question

Does JS support two functions with the same name and different parameters ?

function f1(a, b)
{
// a and b are numbers
}

function f1(a, b, c)
{
// a is a string         


        

Answer 1

Javascript only uses the function that was defined last.

You will need to implement your own logic inside the function to determine which parameters were passed in.
