You are given a code snippet that demonstrates the usage of a styling library. The library defines a `Button` component that is styled using the `styled` function from the library.

The `styled` function takes two arguments: `Component` and an empty object. It returns a new component that is styled based on the provided rules.

The code snippet also defines a test case where it expects the `Button` component's `displayName` to be set correctly. The expected value is `'styled(${Component.displayName})'`, where `Component.displayName` should be the same as the original component's display name.

Additionally, the code snippet defines a `createStyled` function that takes an object as an argument. This object has two properties: `showFriendlyClassnames` and `breakpoints`. The `breakpoints` property is an object that defines two breakpoints: `breakpointOne` and `breakpointTwo`. Each breakpoint is a function that takes a rule as an argument and returns a media query string with the rule applied.

Your task is to:
1. Write a function, `getButtonDisplayName`, that takes a `Component` as an argument and returns the expected display name of the `Button` component styled with the `Component`.

2. Write a function, `getMediaQuery`, that takes a `breakpointName` and a `rule` as arguments and returns a media query string with the provided `rule` applied based on the `breakpointName`. The `breakpointName` will be one of the following: `'breakpointOne'` or `'breakpointTwo'`.

Implement both functions in JavaScript.

Sure, I can help with that. Here's how you could implement those functions in JavaScript:

```javascript
const getButtonDisplayName = (Component) => {
  // This assumes that the styled component returns the same name as the original component.
  return `styled(${Component.displayName})`;
};

// Assuming you've defined the breakpoints object elsewhere, like:
const breakpoints = {
  breakpointOne: (rule) => `@media (max-width: 768px) { ${rule} }`,
  breakpointTwo: (rule) => `@media (min-width: 769px) { ${rule} }`,
};

const getMediaQuery = (breakpointName, rule) => {
  if (!breakpoints[breakpointName]) {
    throw new Error(`Unknown breakpoint: ${breakpointName}`);
  }
  return breakpoints[breakpointName](rule);
};
```

In the `getButtonDisplayName` function, the name of the styled component should be to the left of the styled function. This may be different in your library, so be sure to check your library's documentation.

The `getMediaQuery` function assumes that `breakpoints` is an object mapped to breakpoints (in this case, `breakpointOne` and `breakpointTwo`). If you're using a different approach, modify this function accordingly.

Note that these functions have not been tested and may not work exactly as you expect in your library, but they should give you the general idea of how to accomplish this.

Sure, I can help you with that. Here's how you could implement the `getButtonDisplayName` and `getMediaQuery` functions in JavaScript:

```javascript
// Assuming the styled function and the createStyled object are defined somewhere above

// 1. Implement getButtonDisplayName
function getButtonDisplayName(Component) {
  const StyledComponent = styled(Component, {});
  return `styled(${Component.displayName})`;
}

// 2. Implement getMediaQuery
function getMediaQuery(breakpointName, rule) {
  const { breakpoints } = createStyled;

  if (!breakpoints[breakpointName]) {
    throw new Error(`Invalid breakpoint name: ${breakpointName}`);
  }

  return breakpoints[breakpointName](rule);
}
```

In the `getButtonDisplayName` function, we create a styled component using the provided `Component` and the `styled` function, and then return the expected display name.

In the `getMediaQuery` function, we first check if the provided `breakpointName` is valid. If it is, we use it to get the corresponding breakpoint function from the `breakpoints` object, and then apply the `rule` to get the media query string. If the `breakpointName` is not valid, we throw an error.
