oxc/no-rest-spread-properties Restriction

What it does

Disallow Object Rest/Spread Properties.

Why is this bad?

Object rest/spread properties are a relatively new JavaScript feature that may not be supported in all target environments. If you need to support older browsers or JavaScript engines that don't support these features, using them can cause runtime errors. This rule helps maintain compatibility with older environments by preventing the use of these modern syntax features.

Examples

Examples of incorrect code for this rule:

let { x, ...y } = z;
let z = { x, ...y };

Options

{
  "rules": {
    "no-rest-spread-properties": [
      "error",
      {
        "objectSpreadMessage": "Object spread properties are not allowed.",
        "objectRestMessage": "Object rest properties are not allowed."
      }
    ]
  }
}

• objectSpreadMessage: A message to display when object spread properties are found.
• objectRestMessage: A message to display when object rest properties are found.
