There is a code:

/*Присваиваем метки*/ let label = 0; function setLabel(y, x) { setTimeout(function() { matrix[y][x].label = label; setDivLabel(y, x, label); console.log(matrix[y][x].label); label = label + 1; if (validCell(y - 1, x) && checkCell(matrix[y - 1][x])) { setLabel(y - 1, x); } if (validCell(y + 1, x) && checkCell(matrix[y + 1][x])) { setLabel(y + 1, x); } if (validCell(y, x - 1) && checkCell(matrix[y][x - 1])) { setLabel(y, x - 1); } if (validCell(y, x + 1) && checkCell(matrix[y][x + 1])) { setLabel(y, x + 1); } label = label - 1; }, 500); } setLabel(io.enter[0], io.enter[1]);

When performing the label at each iteration of 0. Why so, please tell me?

The problem is the asynchrony of the setLabel function.

Specifically, the problem is in the string

 label = label - 1;

Which is executed before the setLabel functions are setLabel inside the conditions.

Because of this, after exiting a function and moving to the next, the label value does not change.

You can solve this by saving the label to a local variable before calling setTimeout

Either pass the current label value as a parameter, rather than using a global variable.
