Episode notes

Memory safety is that you're not using more RAM than is available from the computer. Common memory safety violations include de-referencing null or invalid pointers and accessing memory out of bounds. These errors can lead to program crashes, security vulnerabilities, and undefined behaviors. Achieving memory safety implies that the program's memory access read and write are well defined and do not violate memory safety rules.

In this episode of Syntax, Wes and Scott try to stump each other with questions about JavaScript, HTTP status error codes, memory safety, and a bit of web history thrown in.
