Don't understand what this is doing or why it's needed

const weather = require('./weather')

const query = process.argv.slice(2).join('').replace(' ', ''); const query2 = process.argv.slice(2);

weather.getData(query2) weather.getData(query);

//console logs Current temperature in Minneapolis is 40.1F Current temperature in Minneapolis is 40.1F

So I tried logging out both and they gave me the same output. What I don't understand is why .join and .replace is needed. What is it changing?

The "replace" function is there to remove any spaces from the argument. If the argument you provide has no spaces, then it doesn't change anything. But it's there to handle any cases where a space is present in the argument.
