TypeScript's "strictNullChecks" option:ts-string-visitorhelps ensure that you handlenullandundefinedvalues where applicable. To support this, you must compile your project with "strictNullChecks" so that the compiler will treatnullandundefinedas distinct types. This is not optional: code usingts-...

例如1和number,{ foo: number, bar: string }和{ bar: string }都是可以的。 但Record<PropertyKey, unknown>和 tuple type[]不行,string和number也不行。 extendFromType1 和 extendsFrom2 必须是"完全一致"(identical)的。 canExtendBranchType1 is assignable to canExtendBranchType2。
