Hey, hope i am using this forum like it used to be.
At first english is not my first language
I am new to node red and programming.
I want to replace a word in a msg.payload with coordinates i get from an array.
msg.payload = "http://api.openweathermap.org/data/2.5/weather?lat=breite&lon=laenge&appid=xyz ";
var url = msg.payload.replace("laenge",msg.payload[0]).replace("breite",msg.payload[1]);
msg.payload = url
return msg;
so that he sends the url to a http request but with the coordinates.
If u need more information or something let me know! I didnt find a solution for this problem and with my bad knowledge about programming i am done and need 2 ask for help.

msg.payload.replace() is a string function, but msg.payload[0] is an array. They both can not exist at same time. msg.payload is either a string or an array.
is there a way i can make it possible otherwise?

sure use a different variable name for the msg.payload
let url = "http://api.openweathermap.org/data/2.5/weather?lat=breite&lon=laenge&appid=xyz";
url = url.replace("laenge",msg.payload[0]).replace("breite",msg.payload[1]);
msg.payload = url;
return msg;
you are awesome! have a nice day!
is it possible to explain me what "let" does? or give me an link where i can learn this.
Just Copy Past is ok for now but not for the future
