    unused expression, expected an assignment or function call
    Open

    import type { Combo, StoriesHash } from '@storybook/api';
    Severity: Minor
    Found in lib/ui/src/containers/sidebar.tsx by tslint

    Rule: no-unused-expression

    Disallows unused expression statements.

    Unused expressions are expression statements which are not assignments or function calls (and thus usually no-ops).

    Rationale

    Detects potential errors where an assignment or function call was intended.

    Config

    Three arguments may be optionally provided:

    • allow-fast-null-checks allows to use logical operators to perform fast null checks and perform method or function calls for side effects (e.g. e && e.preventDefault()).
    • allow-new allows 'new' expressions for side effects (e.g. new ModifyGlobalState();.
    • allow-tagged-template allows tagged templates for side effects (e.g. this.add\foo`;`.
    Examples
    "no-unused-expression": true
    "no-unused-expression": true,allow-fast-null-checks
    Schema
    {
  "type": "array",
  "items": {
    "type": "string",
    "enum": [
      "allow-fast-null-checks",
      "allow-new",
      "allow-tagged-template"
    ]
  },
  "minLength": 0,
  "maxLength": 3
}

    Missing semicolon
    Open

    import type { Combo, StoriesHash } from '@storybook/api';
    Severity: Minor
    Found in lib/ui/src/containers/sidebar.tsx by tslint

    Rule: semicolon

    Enforces consistent semicolon usage at the end of every statement.

    Notes
    • Has Fix

    Config

    One of the following arguments must be provided:

    • "always" enforces semicolons at the end of every statement.
    • "never" disallows semicolons at the end of every statement except for when they are necessary.

    The following arguments may be optionally provided:

    • "ignore-interfaces" skips checking semicolons at the end of interface members.
    • "ignore-bound-class-methods" skips checking semicolons at the end of bound class methods.
    • "strict-bound-class-methods" disables any special handling of bound class methods and treats them as any other assignment. This option overrides "ignore-bound-class-methods".
    Examples
    "semicolon": true,always
    "semicolon": true,never
    "semicolon": true,always,ignore-interfaces
    "semicolon": true,always,ignore-bound-class-methods

    Do not use comma operator here because it can be easily misunderstood or lead to unintended bugs.
    Open

    import type { Combo, StoriesHash } from '@storybook/api';
    Severity: Minor
    Found in lib/ui/src/containers/sidebar.tsx by tslint

    Rule: ban-comma-operator

    Disallows the comma operator to be used.

    Read more about the comma operator here.

    Rationale

    Using the comma operator can create a potential for many non-obvious bugs or lead to misunderstanding of code.

    Examples

    foo((bar, baz)); // evaluates to 'foo(baz)' because of the extra parens - confusing and not obvious
    switch (foo) {
    case 1, 2: // equals 'case 2' - probably intended 'case 1: case2:'
        return true;
    case 3:
        return false;
}
    let x = (y = 1, z = 2); // x is equal to 2 - this may not be immediately obvious.
    Examples
    "ban-comma-operator": true
