VSCode displays TypeScript errors in two places: inline and in the Problems panel. Viewing an error inline is convenient while coding, whereas the problems panel shows many problems at once.
TypeScript CLI

TypeScript CLI Flags
TypeScript’s tsc can command takes command line flags to alter its behavior. For instance, if we pass a flag like --noUnusedLocals, tsc will ensure that all defined variables are used.
