How to use Marketo template meta variable into javascript

Question

Is it possible to use the Marketo template variable (eg: ${var}) in Javascript? var is defined with a meta tag inside head. I am looking for something like this:

<meta class="mktoBoolean" id="var" mktoName="Show data" false_value="none" true_value="block">


    if(${show_video_1} === "none") {
        console.log("Hello World")
    }

Is this something how it should be done or it needs to have a quotation/backtick?
