Question

I have a list on my controller. I want its size in javascript function. How to get it?

If you are calling javascript function of Visualforce page then you can get the size in visualforce and pass it to your javascript function as an parameter. — Pramod Kumar

I would expect it'll be something like this in the HTML

The use of JSEncode is probably not necessary, but if you are mixing VF output and Javascript it's a good practice.

<script>
   var myJavascriptVariable = {!JSENCODE(myVisualforceList.size)};
</script>

You can use something like this in your javascript -
alert({!lstMySampleList}.length);
