javascript - How to make a sort array and count array button? -


i trying create code sorts products alphabetical order , count number of them class. know how create program 1 or other, when try put them both in doesn't work, i've tried change code around still can't find way work, must doing wrong. appreciated. here current code:

<!doctype html> <html> <body>     <p>printer, tablet, router, computer, phone.</p>      <p>click button sort products alphabetical order.</p>      <button onclick="myfunction()">try it</button>      <p id="demo"></p>      <script>         var products = ["printer", "tablet", "router", "computer","phone"];         document.getelementbyid("demo").innerhtml = products;          function myfunction() {             products.sort();             document.getelementbyid("demo").innerhtml = products;         }     </script>      <button onclick="myfunction()">count number of products!</button>      <p id="demo2"></p>      <script>         var products = ["printer", "tablet", "router", "computer","phone"];         prod1=products.count();          function myfunction() {             products.length();             document.getelementbyid("demo2").innerhtml = products;         }     </script> </body> </html>

welcome programming! fun, except when it's not. gets fun again right after solve problem :)

the problem code is, if separate code inside 2 <script> tags, still read browser single program. in case, notice make have 2 functions same name , 2 'products' arrays, , second 1 overwrite first one.
