I want to call the string property through the function to the console, see if you can suggest

Question

The console says the value is undefined

const pc = {
    brandname: "hp",
    modelName: "hp-221Gt",
    cpu: {
        brandname: "hp",
        motherBoard: "inteLiCore",
        raminGB: 4,
        rominGB: 1024,
        processore: "Octacore",
        processorMaxSpeedinGHz: 3.8,
    },
    powerOn: "yes",
    // powerOff : false,
    newPowerStatus: function (on) {
        this.powerOn = on;
        // this.powerOff = off;
    },
    run: function () {
        return this.newPowerStatus(on);
    }
}

console.log(pc);
console.log("The cpu I use has following specs : ", pc.cpu)
console.log("Is the pc running : ", pc.newPowerStatus.on);

var show = "powerOn";

console.log(pc[show])
console.log(pc.run);

I tried to call the string value of a property in the console through the function.
