eslint/no-useless-concat Suspicious

What it does

Disallow unnecessary concatenation of literals or template literals

Why is this bad?

It’s unnecessary to concatenate two strings together when they could be combined into a single literal.

Examples

Examples of incorrect code for this rule:

var foo = "a" + "b";

var foo = 'a' + 'b' + 'c';

Examples of correct code for this rule:

var foo = 'a' + bar;

// when the string concatenation is multiline

var foo = 'a'
    + 'b'
    + 'c';

How to use

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

Config (.oxlintrc.json)

{
    "rules": {
        "no-useless-concat": "error"
    }
}
