### What it does

Disallow template literal placeholder syntax in regular strings. This rule ensures that
expressions like `${variable}` are only used within template literals, avoiding incorrect
usage in regular strings.

### Why is this bad?

ECMAScript 6 allows programmers to create strings containing variables or expressions using
template literals. This is done by embedding expressions like `${variable}` between backticks.
If regular quotes (`'` or `"`) are used with template literal syntax, it results in the literal
string `"${variable}"` instead of evaluating the expression. This rule helps to avoid this mistake,
ensuring that expressions are correctly evaluated inside template literals.

### Examples

Examples of **incorrect** code for this rule:

```javascript
"Hello ${name}!";
"Hello ${name}!";
"Time: ${12 * 60 * 60 * 1000}";
```

Examples of **correct** code for this rule:

```javascript
`Hello ${name}!`;
`Time: ${12 * 60 * 60 * 1000}`;
templateFunction`Hello ${name}`;
```
