#2

@sharma.deepti182 change the req.send to res.send, you use the response to send not the request. Change that and it will work

#3

I changed it to res.send but still it isn’t working

#4

@sharma.deepti182 try the following changes

const express = require('express')
const app = express()

app.get('/', (req, res) => {
    res.send("Hello Deepti")
})
app.get('/greet', (req, res) => {
    let person = 'guest'
    if(req.query.person) {
        person = req.query.person
    }
    // res.send outside of if block
    res.send('Good evening' + person)
})
app.listen(4444, ()=>{
    console.log('Server started on http:localhost:4444')
})
