How to: (איך לעשות:)

To print debug output in Elm, use Debug.toString to convert values to strings and Debug.log to print them with a message.

import Html exposing (text)

main =
  let
    valueToCheck = 42
    debugMessage = Debug.log "Checking value" (Debug.toString valueToCheck)
  in
  text debugMessage

Sample output in the console would be: "Checking value: 42"

Deep Dive (צלילה עמוקה)

Elm’s debug facilities are built for developer convenience. Historically, Elm pushed functional programming in browsers, where debug tools were scarce. Alternatives like browser debugger or custom functions exist but aren’t as seamless. Debugging in Elm aims for simplicity: Debug.log is informational, for values at runtime, while Debug.toString serializes almost anything. Elm’s approach emphasizes readable, reliable output, ensuring a smoother debug experience compared to lower-level language practices.
