Typescript and non string Environment Variable parsing

Leaving this here as just a simple get an env variable and 'cast' to boolean is a PITA. But this is what I ended up with...

const skipTestSetting = process.env.BOT_SKIP_KNOWN_FAILED_TESTS;  
export const shouldSkip = (t: TestObj): boolean => {  
    const noSkip = skipTestSetting === 'true'
        ? true :  typeof skipTestSetting === 'string'
        ? !!+skipTestSetting
        : !!skipTestSetting;
