Write your if condition like this typeof(num)== 'number'

try this code <!DOCTYPE html> <html> <head> <title>Page Title</title> </head> <body> <script>var num="randomtedt"; if (typeof(num) == "number"){ alert("c un nombre") ; } else { alert("pas un nombre") ; }</script> </body> </html> differences are == instead of = "number" instead of number == compare opertation number is a string not a variable
