Using the model below, I need to use the where operator when querying Firestore. However, the where attribute is nested based on the following variable code:
where("category", "==", "Something"),
const language = "EN"
{
EN: {
category: "Something in english"
},
FR: {
category: "Something in french"
}
}

To be able to query a collection based on the values present in the map, you should use the
wherefunction call like this:where("EN.category", "==", "Some Category")If you need to change the language, then you should consider using variables instead of hard-coded values. In code it should look like this:
where('${language}.category', "==", "Some Category")
