How to make an If statement check for if a variable equals a negative number; issue making an adventure game with X,Y coordinates - if-statement

Question

I'm new to Javascript (and coding in general), and I'm trying to make a pretty basic in-browser adventure game, but immediately I've encountered a problem. I wanted it to plot your location as if on an X,Y graph so I could easily mark out a map for it later with coordinates. So, you start at 0,0, and when you move West it changes to -1,0, so on, and I'm using If statements to check your location. But, it always assumes you're at the lowest negative possible, and so always says you're at 'Room 3'.
I think it does this because it doesn't recognise the - in the check as part of the number, and instead thinks you're asking if it equals the number minus itself, which would be zero, which is the game's default position. But, at the same time, it still thinks you're at the lowest possible position even if you move off 0,0, so I don't know. If that is the case, I would like to know how to fix it, and if that isn't the case, I would like to know what the real problem is.
Below is the entire program so far. This is my first time really trying to code something by myself, with no tutorial involved, so I apologise for how training-wheels-y it is.
let x=0
let y=0
let time=0
let button = document.getElementById('button');
let buttonNorth = document.getElementById('buttonNorth');
let buttonWest = document.getElementById('buttonWest');
let buttonEast = document.getElementById('buttonEast');
let buttonSouth = document.getElementById('buttonSouth');
button.onclick = function() {
reporter()
locatron()
}
buttonNorth.onclick = function() {
updateNorth()
reporter()
locatron()
}
buttonWest.onclick = function() {
updateWest()
reporter()
locatron()
}
buttonEast.onclick = function() {
updateEast()
reporter()
locatron()
}
buttonSouth.onclick = function() {
updateSouth()
reporter()
locatron()
}
function reporter() {
console.log(`location is: ${x},${y}`)
console.log(`time is: ${time}`)
}
function updateNorth() {
y = y+1
time=time+1
}
function updateWest() {
x = x-1
time=time+1
}
function updateEast() {
x = x+1
time=time+1
}
function updateSouth() {
y = y-1
time=time+1
}
function locatron() {
if(x==0,y==0) {
totalDescription.innerHTML = `Room 1`
}
if(x==-1,y==0) {
totalDescription.innerHTML = `Room 2`
}
if(x==-2,y==0) {
totalDescription.innerHTML = `Room 3`
}
else {
totalDescription.innerHTML = `This area has not been written yet.`
}
}
I've tried turning the number in the If statement into a string, but it just does the same thing. The only way I can get it to display any message other than 'Room 3' is by moving it along the Y axis, at which point it changes to my equivalent of an error message, 'This area has not been written yet.'. I also tried looking the problem up, but the wording on it is so finnicky that the only results I would get back are how to 'check if a variable is negative', which is not at all what I want.
I appreciate any help I can get.
