#Rule Details

Disallows template literal placeholder syntax (${expression}) inside regular strings. This is almost always a mistake where the developer intended to use a template literal (backtick-delimited string) but accidentally used single or double quotes instead, so the placeholder is treated as a literal string rather than being interpolated.

Examples of incorrect code for this rule:

var greeting = 'Hello, ${name}!';

var query = 'SELECT * FROM ${table}';

var msg = 'The value is ${a + b}';

Examples of correct code for this rule:

var greeting = `Hello, ${name}!`;

var query = `SELECT * FROM ${table}`;

var literal = 'This is a dollar sign: ${}'; // intentional
