To show how things can be made shorter:


As an example I'll take the 'file existing' routine shown by Chris Boulton.

code:

---

// Checking if a file exists:

function file_exists(file)
{
    var fileSys = new ActiveXObject("Scripting.FileSystemObject");
    if(fileSys.FileExists(file))
    {
        return true;
    }
    else
    {
        return false;
    }
}

---

If you use an IF THEN ELSE structure to check on a function which only returns true or false on its own, you can do:

code:

---

return fileSys.FileExists(file)

---

Since filesys is an object which you have defined before and since this is only used once, you don't specifically need it to be defined as a variable but you can use it directly:

code:

---

return new ActiveXObject("Scripting.FileSystemObject").FileExists(file)

---

All this makes that the function is reduced to only 1 line:

code:

---

function file_exists(file)
{
    return new ActiveXObject("Scripting.FileSystemObject").FileExists(file);
}

---
