Features:
isCompilerOptionEnabledTypeguards are now split into multiple submodules for each version of TypeScript (starting with 2.8.0). That means you can now import directly from "tsutils/typeguard/2.8" to get compatible declaraton files for TypeScript@2.8. For more information please read the relevant section in README.md.
Features:
isTupleType, isOptionalTypeNode, isRestTypeNode, isSyntheticExpression (currently available from "tsutils/typeguard/3.0")isStrictCompilerOptionEnabledAvoid crash caused by removed function in typescript@3.0.0.
Added support for TypeScript@3.0.0 nightly builds.
