How to interpret file content as template string?

Question

I was wondering if there was a way to use the content read from a file as a template string?

Ex: my file hello_world.txt :

hello world from ${name}

And then something like (with nodejs) :

var name = 'Jérémie';
var fileContent = fs.readFileSync('./hello_world.txt');
debug(fileContent); // Hello word from Jérémie

It seems possible, using the eval() function, but I don't really like this solution.

Thanks

Assuming you trust the files you are reading, you can accomplish this with eval:

let message = "${greeting} World",
    greeting = "Hello";
    
alert(eval(`\`${message}\``))
