    // -- Strong Warnings --
    // These rules should almost never be needed, but may be included due to legacy code.
    // They are left as a warning to avoid frustration with blocked deploys when the developer
    // understand the warning and wants to deploy anyway.

    // Warn when an empty interface is defined. These are generally not useful.
    "no-empty-interface": {"severity": "warning"},

    // Warn when an import will have side effects.
    "no-import-side-effect": {"severity": "warning"},

    // Warn when variables are defined with var. Var has subtle meaning that can lead to bugs. Strongly prefer const for
    // most values and let for values that will change.
    "no-var-keyword": {"severity": "warning"},

    // Prefer === and !== over == and !=. The latter operators support overloads that are often accidental.
    "triple-equals": [true, "allow-null-check"],

    // Warn when using deprecated APIs.
    "deprecation": {"severity": "warning"},

    // -- Light Warnings --
    // These rules are intended to help developers use better style. Simpler code has fewer bugs. These would be "info"
    // if TSLint supported such a level.

    // prefer for( ... of ... ) to an index loop when the index is only used to fetch an object from an array.
    // (Even better: check out utils like .map if transforming an array!)
