The variable passed to the .pug mixin is not visible in the script, what can I do?

Question

JavaScript

this is a regular mixin in a pug file, every time I add it to index.pug I need this function to be called with the same parameters that are passed to the mixin. but these variables are not visible in the script, maybe there is another option?
Now I do it this way - every time I call the function along with the mixin in index.pug

Answer 1

mixin chart(value)
  script.
    updateChart(#{value})
    
+chart(10)

In general, it is not safe to generate such js code on the server side. It is better to write initial values, for example, to hidden inputs and read values ​​from them with some validation.
