// A set of words can be grouped together in different cases.

// For example, "hello there" in snake case would be written "hello_there"
// UPPER_SNAKE_CASE means taking a string and writing it in all caps with underscores instead of spaces.

// Implement a function that:

// Given a string input like "hello there"
// When we call this function with the input string
// it returns the string in UPPER_SNAKE_CASE, so "HELLO_THERE"

// Another example: "lord of the rings" should be "LORD_OF_THE_RINGS"

// You will need to come up with an appropriate name for the function
// Use the MDN string documentation to help you find a solution
// This might help https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/toUpperCase

// NOTES: 
// "hello there" should become "HELLO_THERE"
// I need to turn all letters into CAPITALS and replace the space " " with underscore "-"

// From the MDN documentation:
// I can use the toUpperCase() to turn the tring into all CAPS.
// I can use the replaceAll() to replace all the spaces with underscores.

// Good function name:
// toUpperSnakeCase - this name is decriptive and indicates that the function will convert a string to upper snake case.

function toUpperSnakeCase(str) {
    return str.toUpperCase().replaceAll(" ", "_");
}

console.log(toUpperSnakeCase("hello there"));
// HELLO_THERE

console.log(toUpperSnakeCase("lord of the rings"));
// LORD_OF_THE_RINGS
