eslint/no-multi-str Style

What it does

Disallow multiline strings.

Why is this bad?

Some consider this to be a bad practice as it was an undocumented feature of JavaScript that was only formalized later.

Examples

Examples of incorrect code for this rule:

var x =
  "Line 1 \
 Line 2";

How to use

To enable this rule using the config file or in the CLI, you can use:

Config (.oxlintrc.json)

{
  "rules": {
    "no-multi-str": "error"
  }
}

Config (oxlint.config.ts)

import { defineConfig } from "oxlint";

export default defineConfig({
  rules: {
    "no-multi-str": "error",
  },
});
