Tell us what’s happening:

it work correctly but not passed the test
sellPlants(ballerina, “small”, 25) should return Not enough small size pots for Lavandula stoechas ‘Ballerina’. Only 10 left..
4. sellPlants(ballerina, “small”, 10) should return Catalog successfully updated. and subtract 10 from the small property of the object associated with the ballerina key in the catalog.
5. You should not directly modify the key-value pairs inserted in your catalog map.

Your code so far

const ballerina = {
    commonName: "Spanish lavender",
    scientificName: "Lavandula stoechas",
    cultivar: "Ballerina"
}

const prettyPolly = {
    commonName: "Spanish lavender",
    scientificName: "Lavandula stoechas",
    cultivar: "Pretty Polly"
}

const willowVale = {
    commonName: "Spanish lavender",
    scientificName: "Lavandula stoechas",
    cultivar: "Willow Vale"
}

const hidcote = {
    commonName: "English lavender",
    scientificName: "Lavandula angustifolia",
    cultivar: "Hidcote"
}

const imperialGem = {
    commonName: "English lavender",
    scientificName: "Lavandula angustifolia",
    cultivar: "Imperial Gem"
}

const royalCrown = {
    commonName: "French lavender",
    scientificName: "Lavandula dentata",
    cultivar: "Royal Crown"
}

const catalog = new Map();
catalog.set(ballerina, { small: 20, medium: 15, large: 12 });
catalog.set(prettyPolly, { small: 31, medium: 14, large: 24 });
catalog.set(willowVale, { small: 3, medium: 5, large: 0 });
catalog.set(hidcote, { small: 33, medium: 13, large: 18 });
catalog.set(imperialGem, { small: 19, medium: 35, large: 28 });
catalog.set(royalCrown, { small: 40, medium: 22, large: 9 });

// User Editable Region

const sellPlants = (plant, size, potsNo) => {
    const name = `${plant.scientificName} '${plant.cultivar}'`
    const pots = catalog.get(plant);
    if (pots[size] - potsNo < 0) {
        return `Not enough ${size} size pots for ${name}. Only ${pots[size]} left.`
    } else {
        pots.size-=potsNo
        return "Catalog successfully updated."
    }
}

console.log(sellPlants(ballerina, "small", 10));

console.log(catalog)

Looks like the logic is fine, but there are two gotchas: you’re updating pots.size instead of pots[size], and you’re mutating the object returned from Map.get(). The tests expect you to create a copy, update it, and set it back into the Map. Also, some tests depend on the catalog state, not just the return value.
