WebAssembly is a W3C standard that complements JavaScript for performance-heavy tasks while running in the same security sandbox.
A WebAssembly module interacts with an external environment like JavaScript through imports and exports for functions, memory, and global variables.
WebAssembly modules have an interchangeable binary format (.wasm) for execution and a human-readable textual format (.wat) for debugging.
WebAssembly uses a stack machine for execution, where instructions manipulate values on a stack to perform computations.
A live coding demonstration shows how to implement the recursive Fibonacci algorithm using WebAssembly's textual format (.wat).
WebAssembly constructs loops using structured block and loop statements with indexed labels for branching, which replace traditional goto statements.
This live coding example demonstrates how to iterate through an array in memory to find its maximum value using WebAssembly bytecode.
The speaker answers audience questions about connecting multiple modules, using WebAssembly for secure software supply chains, and the best languages to start with.
