### What it does

Checks for usage of legacy patterns for mathematical operations.

### Why is this bad?

Modern JavaScript provides more concise and readable alternatives to legacy patterns.

Currently, the following cases are checked:

* Prefer `Math.log10(x)` over alternatives
* Prefer `Math.hypot(…)` over alternatives

### Examples

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

```javascript
Math.log(x) * Math.LOG10E;
Math.sqrt(a * a + b * b);
```

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

```javascript
Math.log10(x);
Math.hypot(a, b);
```

## How to use

## Version

This rule was added in v0.1.1.
