Hi,

Compilation Status Page gives me a warning when i use ‘\<=’ check in pure javascript:

Test.dotvvm:

```auto
...
<body>
    <div class="container">
        {{value: Now}}
    </div>

<script>
    function AnyMethod() {
        var a = 10;
        var b = 20;
        if (a <= b) {
            console.log("a is less than or equal to b");
        } else {
            console.log("a is greater than b");
        }
    }
</script>

</body>
</html>

```

The warning message is as follows:

 ![ScreenShot_20260413134417](https://forum.dotvvm.com/uploads/default/original/1X/95008515f6b2a3f50d218440a5e5bbbaca9977d9.jpeg)

If I use ‘\<’ instead of '\<=", no warning is generated.

‘\<=’ seems to be crawled across the entire page. Perhaps you can prevent it from being crawled within the script block.  
Regards.

This should be resolved in version 5 (see [#1900](https://github.com/riganti/dotvvm/pull/1900)), you can try the preview version if you want to

Yes, you’re right. It didn’t give any warnings in the preview version.
