How to use this inside a function which is inside a class method in Javascript

Question

I'd like to use this to referring to the class properties while instead is referring to the function itself. How can I do?

class Person {

    isWalking = false
    steps = 10

    walk() {
        this.isWalking = setInterval(function () {
            if (this.steps <= 1) {
                clearInterval(this.isWalking)
                this.isWalking = false
            }
            --this.steps
            console.log(this.steps)
        }, 1000)
    }

}

Just change the callback you give to `setInterval` into an arrow function. — VLAZ, Aug 12 '21 at 14:57

Covert your setInterval callback to an arrow function
