I created an express app that use a function searchUrls() from another JavaScript file.
this function return a variable Res.
i can show it's value by res.send(Res) or res.json(Res).
but i want to pass the value to another variable.
const express = require('express');
const app = express();
const script = require('./script');
app.get('/search/:itemID', (req, res) =>
script
.searchUrls(req.params.itemID)
.then(Res =>
res.json(Res);
);
);
const port = process.env.PORT || 3000;
app.listen(port, () =>
console.log(`Listening on $port`);
)javascript node.js express

I am a bit confused about what you want to achieve, do you want to save the variable "Res", add some extra information to it or?

The terminology is confusing, so it's unclear what you're trying to achieve.searchUrlsdoesn't return a variable, it returns a promise.Resisn't a variable, it's a parameter. another variable - what is that?

@rachidelaid What does 'work with it' mean? Do you want to cache it or else? Where you want to use this 'variable'? The code you posted doesn't illustrate your intentions, and the description doesn't really help to understand them.
