Here is an example of a virtual abacus written in JavaScript that can perform basic operations:
javascript
Copy code
class Abacus {
constructor() {
this.value = 0;
}
add(val) {
this.value += val;
}
subtract(val) {
this.value -= val;
}
reset() {
this.value = 0;
}
getValue() {
return this.value;
}
}
const myAbacus = new Abacus();
myAbacus.add(5);
console.log(myAbacus.getValue()); // 5
myAbacus.subtract(2);
console.log(myAbacus.getValue()); // 3
myAbacus.reset();
console.log(myAbacus.getValue()); // 0
This simple implementation of an abacus uses a class with methods to add, subtract, reset and get the current value of the abacus. This can serve as a starting point for building a more complex and interactive virtual abacus for children to learn and develop their mathematical skills.
