 * generateQueryParams({ key1: 'value1', key2: 42 }); // "?key1=value1&key2=42"
 * generateQueryParams({ key1: ['value1', 'value2'], key2: 42 }); // "?key1=value1&key1=value2&key2=42"
 * generateQueryParams({ key1: '', key2: null }); // ""
 * generateQueryParams({ key1: true, key2: false }); // "?key1=true&key2=false"
 * generateQueryParams({ filters: { category: 'laptop', price: 1000 } }); // "?category=laptop&price=1000"
