Question

Is there any way to create the query parameters for doing a GET request in JavaScript?

Just like in Python you have urllib.urlencode(), which takes in a dictionary (or list of two tuples) and creates a string like 'var1=value1&var2=value2'.

Here you go:

function encodeQueryData(data) {    const ret = [];    for (let d in data)      ret.push(encodeURIComponent(d) + '=' + encodeURIComponent(data[d]));    return ret.join('&'); } 

Usage:

const data = { 'first name': 'George', 'last name': 'Jetson', 'age': 110 }; const querystring = encodeQueryData(data);
