How can I create a stringified query string of array values?

Question

What I ultimately want to have is:

import qs as 'qs'

qs.stringify({
      country: 'us',
      currency: 'USD',
      'kw[]': 'apple',
      'kw[]': 'banana',
      'kw[]': 'pear',
    })

But currently, I have:

const keywords = ['apple', 'banana', 'pear']

How can I convert that to the kw[] syntax?

I would use reduce personally. You can reduce the array to an object. — evolutionxbox

Not right now no. The key is to return an object and not an array from the reducer. — evolutionxbox

import qs from 'qs';
const keywords = ['apple', 'banana', 'pear'];
const queryObject = { country: 'us', currency: 'USD', kw: keywords };
const queryString = qs.stringify(queryObject);
console.log(queryString);

The above will output:

country=us&currency=USD&kw%5B0%5D=apple&kw%5B1%5D=banana&kw%5B2%5D=pear

Decoded, it looks like this:

country=us&currency=USD&kw[0]=apple&kw[1]=banana&kw[2]=pear
