Two function with same name having different output on the same page. Which one will take precedence in js

Question

function a(){alert(1);} function a(){alert(2);}

Answer 1

The last one. In this case, it'll alert 2.
When you declare 2 functions with the same name, the last one will overwrite the preceeding one.

Answer 2

the one that is defined later!
