}noUncheckedIndexedAccess - prevent issue when object is possible undefined
export const myObj: Record<string, string[]> = {};
myObj.foo.push("bar"); // without noUncheckedIndexedAccess = true won't be an error strict - Enable all strict type-checking options
skipLibCheck - Skip type checking of all .d.ts files. This enhances performance as TypeScript doesn't perform type checking on npm package types.
