Sharing some naming conventions is a key point to make it possible for a team to efficiently collaborate. This rule allows to check that all variable names match one of the following patterns: `lowerCamelCase`, `PascalCamelCase` or `UPPER_CASED`. This rule also allows leading underscore.

## Noncompliant Code Example

    const foo_bar = 1;
    const baz_ = 2;

## Compliant Solution

    const fooBar = 1;
    const _baz = 2;
