I'm currently working with the discord.js library.
I guess I can call it by this name, but whenever I want to access a file, this doesn't work.
Let's say I have a file called calc.js and I want to access the main.js file and take a variable out of there using exports and require it to just take the value out of it.
But I haven't found even one way online to modify the variables and return another value to the file.
Can someone help me?
As noted, JavaScript doesn't pass every variable by reference. If you need to access a primitive value like a number, you could declare it as a local variable and export functions to access and modify it. Something like this rough example:
let count = 0;
module.exports = {
get: () => count,
increment: () => ++count
};
const { get, increment } = require('./increment.js');
console.log(get());
console.log(increment());
console.log(get());
Edit: You should probably not name your accessor get, as that's the key word used to describe getters in ES6. Or better yet, turn such a get function into a getter with a more suitable name.
You can use a dictionary/map:
let variables = {};
export { variables };
const { variables } = require('./variables.js');
variables.x = 'whatever';
