    "removeComments": true,
    // Strips all comments from TypeScript files when converting into JavaScript- you rarely read compiled code so this saves space
    "target": "ES6",
    // Target environment. Most modern browsers support ES6, but you may want to set it to newer or older. (defaults to ES3)

    // Module resolution
    "baseUrl": "./",
    // Lets you set a base directory to resolve non-absolute module names.
    "esModuleInterop": true,
    // fixes some issues TS originally had with the ES6 spec where TypeScript treats CommonJS/AMD/UMD modules similar to ES6 module

    // Pretty much always node for modern JS. Other option is "classic"
    "paths": {},
    // A series of entries which re-map imports to lookup locations relative to the baseUrl

    // Source Map
    "sourceMap": true,
    // enables the use of source maps for debuggers and error reporting etc
    "sourceRoot": "/",
    // Specify the location where a debugger should locate TypeScript files instead of relative source locations.

    // Strict Checks
    "alwaysStrict": true,
    // Ensures that your files are parsed in the ECMAScript strict mode, and emit “use strict” for each source file.
    "allowUnreachableCode": false,
    // pick up dead code paths
    "noImplicitAny": true,
    // In some cases where no type annotations are present, TypeScript will fall back to a type of any for a variable when it cannot infer the type.
    "strictNullChecks": true,
    // When strictNullChecks is true, null and undefined have their own distinct types and you’ll get a type error if you try to use them where a concrete value is expected.

    // Linter Checks

    "noUncheckedIndexedAccess": true,
    // accessing index must always check for undefined
    "noUnusedLocals": true,
