¿Alguien puede explicar el uso de la palabra clave 'esta' en el siguiente código?

Soy un principiante en javascript. ¿Alguien puede explicar el uso de la palabra clave 'this' en el siguiente código y por qué el código no funciona sin la palabra clave 'this'?

 function Count() { var count = 0; this.incrementCount = () => { count++; console.log(count); }; this.decrementCount = () => { count--; console.log(count); }; } var count1 = new Count(); count1.incrementCount(); count1.decrementCount();
