Hi team,  
I was trying to solve factorial number of my own logic and I get some weird result, below is my code please help me with this

function Fact(n){  
var m = n;  
[//console.log](https://console.log)(m) // 5 initially  
if(m === 1){return 1}  
for(var i=m; i\>=1; i–){  
m\*=i-1;  
[//console.log](https://console.log)(m); // I get 120 here  
}  
return m; // this return statement is always 0, I’m not getting 120  
}  
Fact(5);

Hello @socalledsoftwaredeveloper

you doing great well done just some little issue

1. the main issue is here

```auto
for(var i=m; i>=1; i–){ // i guess there typo here it should be i-- not i-
m*=i-1; // when i be 1 then m will be m*=i-1 (which will be 0) which make m to be 0

```

1. there a missing semicolon at the end of `return 1`;

2. notice that your email is visible so try to change your profile setting to hide it

3. it would be better to share your code on any online service like [codepen.io](http://codepen.io) jsfiddle github glitch in your future post

hope that help and have a nice day 🙂

you very welcome @socalledsoftwaredeveloper

i am not the team i am just a learner same as you 😉

i forget to mention that it better to use let instead of var cause it give you a block level scope
