What is the output of this code? var _run=0 ; function _runchange(){ var _run=1;} console.log(_run);

Answer 1

good luck

Answer 2

it is 0 because you declared a new variable called _run with the same name with the global variable

so it will not affect on the global even if you call _runchange function

to access global variable use window object
example:
window._run=5;

this makes the global _run equals to 5
