I couldn't convert this syntax to js or ts:
def get_index(self):
path = self.get_request_path()
if "/_async_search" in path and "/_search":
# no index we wildcard
return next((sub_part for sub_part in path.split("/") if sub_part != ""), "*")
return None
I think the main complication to do the javascript translation of your python code is to lazy load the list returned by path.split("/") like it's done in your python code.
For that, you can use a generator function like the following:
function* first_substring(path) {
for(substring of path.split("/")){
if(substring !== ""){
yield substring;
}
else{
yield "*";
}
}
}
Then your javascript translation would be something like:
function get_index(){
const path = this.get_request_path();
if(path.indexOf("/_async_search") !== -1 && "/_search"){
return first_substring(path).next().value;
}
return None
}
