Runtime Error
Noun · Development
Definitions
An error that occurs while a program is executing, as opposed to at compile time or during static analysis. Common examples include null pointer dereferences, division by zero, out-of-bounds array access, and unhandled exceptions.
In plain English: A problem that only shows up when the program is actually running, not when it's being built.
Example: "The code compiles clean but throws a runtime error on the first request — it's a nil map access when the config key is missing."
