/**
Convert a string literal to snake-case.

This can be useful when, for example, converting a camel-cased object property to a snake-cased SQL column name.

@example
```
import {SnakeCase} from 'type-fest';

// Simple

const someVariable: SnakeCase<'fooBar'> = 'foo_bar';

// Advanced

type SnakeCasedProperties<T> = {
    [K in keyof T as SnakeCase<K>]: T[K]
};

interface ModelProps {
    isHappy: boolean;
    fullFamilyName: string;
    foo: number;
}

const dbResult: SnakeCasedProperties<ModelProps> = {
    'is_happy': true,
    'full_family_name': 'Carla Smith',
    foo: 123
};
```
