no-array-size-assignment

Reports append-by-size assignments and points you to push.

Rule details Problem

The rule matches this exact append pattern:

array[array.size()] = value;

It also works with member chains such as state.items[state.items.size()] = item;.

It does not match lookalikes like array[array.size() - 1] = value, array[other.size()] = value, or array[array.size()] += value.

Configuration

import ceaseNonsense from "eslint-plugin-cease-nonsense";

export default [
  {
    plugins: {
      "cease-nonsense": ceaseNonsense,
    },
    rules: {
      "cease-nonsense/no-array-size-assignment": ["error", {
        "allowAutofix": true
      }],
    },
  },
];

Option

Option	Default	What it does
`allowAutofix`	`false`	Rewrites the assignment to `.push(...)` when the target is safe to evaluate once

The automatic fix only runs when the assignment is a standalone expression statement and the array target is a simple, non-optional reference chain such as array, this.items, store["items"], or registry[keyRef.value].

Examples

Incorrect

inventory[inventory.size()] = item;
state.items[state.items.size()] = nextItem;

Correct

inventory.push(item);
state.items.push(nextItem);
