How to specify a relative path to a file?

Question

JavaScript

Good evening, I'm trying to specify the relative path of the project. I have two folders. In the handlers folder I have a handler.js file with the following code:

const commandFiles = fs.readdirSync(`../commands/`).filter(file => file.endsWith('.js')); 

        for (const file of commandFiles) {
            const command = require(`../commands/${file}`); 
        
            client.commands.set(command.name, command);
        }

And the second folder commands. To which I am trying to specify a relative path.
This code does not work, it gives an error that the file or directory was not found. Tell me how can this be done?
