Your question makes no sense.
The web uses HTTP as a universal protocol for client-server web transactions.
The server and the client are independent objects/ entities that can exchange data because of HTTP. Javascript or not, curl or not, wget or not? These topics are an independent and mostly unrelated issue.
That is why there are communication protocols, to decouple the application and underlying programming language from the client-server comms. In this case:
Hypertext Transfer Protoco (HTTP)
So, it should not matter if talking "shoestring" to "elephant ear" as long as both the client and the server adhere to the same HTTP protocol standard(s).
Anyway, underlying most Javascript implements like node.js (on the server side) is C++ and the same is true of wget, curl, etc. At the core of most of all this is C++ (not that it matters).
Regardless of the programming language, HTTP-based client-server applications can communicate (exchange data) because they follow the same set of communication protocol standards.

curlopt_stream_weight
CURLOPT_STREAM_WEIGHT(3) curl_easy_setopt options CURLOPT_STREAM_WEIGHT(3)
NAME
CURLOPT_STREAM_WEIGHT - set numerical stream weight
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_STREAM_WEIGHT, long weight);
DESCRIPTION
Set the long weight to a number between 1 and 256.
When using HTTP/2, this option sets the individual weight for this particular stream used by the easy handle. Setting and using weights
only makes sense and is only usable when doing multiple streams over the same connections, which thus implies that you use CURLMOPT_PIPE-
LINING(3).
This option can be set during transfer and will then cause the updated weight info get sent to the server the next time a HTTP/2 frame is
sent to the server.
See section 5.3 of RFC 7540 for protocol details: https://httpwg.github.io/specs/rfc7540.html#StreamPriority
Streams with the same parent should be allocated resources proportionally based on their weight. So if you have two streams going, stream A
with weight 16 and stream B with weight 32, stream B will get two thirds (32/48) of the available bandwidth (assuming the server can send
off the data equally for both streams).
DEFAULT
If nothing is set, the HTTP/2 protocol itself will use its own default which is 16.
PROTOCOLS
HTTP/2
EXAMPLE
TODO
AVAILABILITY
Added in 7.46.0
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
