no-constant-condition (ESLint: no-constant-condition)

disallow use of constant expressions in conditions (recommended)

Rationale

A constant expression (for example, a literal) as a test condition might be a typo or development trigger for a specific behavior. For example, the following code looks as if it is not ready for production.

Config

• "checkLoops" Setting this option to false allows constant expressions in loops (default: true).

Examples

"no-constant-condition": true

"no-constant-condition": [true, { "checkLoops": false }]

  "type": "object",
