如何修复Eslint偏爱销毁

Question

我应该如何重写以下行，以避免出现此错误

ctrl.formData.type = ctrl.types[0];

Answer 1

Tweaking the rule configuration based on the prefer-destructuring docs ought to avoid this case. This change would disable the rule for assignments like your example while keeping it for the more common case of declarations:

"prefer-destructuring": ["error", {
  "AssignmentExpression": {
    "array": false,
    "object": false
  }
}]

If you want to keep the rule configured as-is, this one-liner works:

[ctrl.formData.type] = ctrl.types;

Answer 2

This should work:

let [ type ] = ctrl.types;
ctrl.formData.type = type;
