vue/no-useless-concat

Disallow useless string concatenation in template expressions.

Applies to: Vue SFC templates and blocks, with script context where the rule requires it.

Bad

Two string literals are concatenated at runtime.

<template>
  <p>{{ "hello" + " world" }}</p>
</template>

Good

One literal represents the same text.

<template>
  <p>{{ "hello world" }}</p>
</template>
