Type Checking
A static analysis technique that verifies type consistency among variables and function signatures, used to detect type errors before compilation.
Timeline (last 90 days)
Tightening type checking does not equal real browser actions having passed; type checking cannot replace behavior tests, and a successful build does not prove a button won't submit twice.
Automated checks (lint, tests, type checking) can intercept low-level errors but cannot replace human judgment of the reasonableness of business logic and the correctness of a solution.
Agents need runnable checks as a feedback loop, including tests, builds, type checks, linters, and clear error messages.
Type checking verifies the type consistency of variables, parameters, and return values before compilation or execution and can catch interface misuse; lint uses static analysis to find issues such as unused variables, suspicious null handling, and style violations.
