Pug: what does this line do?

Question

Node.js

The pug documentation is frail. Can you elaborate on how this works:

// Compile the source code
const compiledFunction = pug.compileFile('template.pug');

Why do we then pass the compiledFunction object with template variables, because it's not like a function? Can anyone guess why the work of the most popular node templating engine was organized this way?

Answer 1

const compiled Function = pug.compileFile('template.pug');

Doesn't bother anything? =)
We get the function by compiling the template. We pass an object with variables there and get the result. I think everything is fine =)
