get specific data from https body

I want to get the median_price value from link

My code:

const https = require('https');
var item = ('M4A1-S | Decimator (Field-Tested)')
var body = '';
https.get('https://steamcommunity.com/market/priceoverview/?appid=730&market_hash_name=' + item, res => {
    res.on('data', data => {
        body += data;})
    res.on('end', () => console.log(body));
}).on('error', error => console.error(error.message));

output is:

{"success":true,"lowest_price":"$5.17","volume":"469","median_price":"$5.09"}

I want it to be:

5.09

so I can add multiple values together. What do I need to change?

Turn the result into javascript object using JSON.parse, access it as usual and turn it to number using parseFloat (you can use substr method to remove the leading $)

parseFloat(JSON.parse(body).median_price.substr(1))

so in your code

res.on('end', () => console.log(parseFloat(JSON.parse(body).median_price.substr(1)));
