¿Cómo actualizar solo el índice dado de la matriz 2d en javascript?

Creé una matriz 2d usando Array constructor y la llené con una matriz dentro.

 const a = new Array(26).fill(new Array(2).fill(-1));

Cuando trato de hacer esto a[0][0] = 0 el índice 0 de las 26 matrices ha cambiado. ¿Cómo evito eso?

 const a = new Array(26).fill(new Array(2).fill(-1)); a[0][0] = 0 console.log(a)
