useConsistentObjectDefinition

JavaScript (and super languages)

Summary

Diagnostic Category: lint/nursery/useConsistentObjectDefinition
This rule has a safe fix.
The default severity of this rule is error.
Sources:
- Inspired from object-shorthand

Description

Require the consistent declaration of object literals. Defaults to explicit definitions.

ECMAScript 6 provides two ways to define an object literal: {foo: foo} and {foo}. The two styles are functionally equivalent. Using the same style consistently across your codebase makes it easier to quickly read and understand object definitions.

Options

Use the options to specify the syntax of object literals to enforce.

1
{
2
    "options": {
3
        "syntax": "explicit"
4
    }
5
}

syntax

The syntax to use:

explicit: enforces the use of explicit object property syntax in every case.
shorthand: enforces the use of shorthand object property syntax when possible.

Default: explicit
