object javascript 中未定义的 boolean

Question

I attempted the following question but i am stuck on defining a boolean. The question is as follows:

QUESTION

Define a function getWalletFacts that receives wallet, an object.

getWalletFacts should return a sentence stating the wallet's color and cash state.

My attempted code

const hascash = Boolean();

let wallet ={
    color:"",
    hascash:true||false,
    write: function(sentence){
        console.log(sentence);
    }
};
function getWalletFacts(wallet){
    let sentence= "my wallet is " + wallet.color+ " and  " + wallet.hascash; 
    return sentence;
}

whenever i check my answer it tells me that hascash is undefined ie

    Expected: "My wallet is Black and has cash"
        Received: "my wallet is Black and  undefined"

from my understanding of the question hascash accepts a boolean

Any help would be kindly appreciated!

Given Example

const wallet = {
    color: "Black",
    hasCash: true
};

getWalletFacts(wallet); // => 'My wallet is Black and has cash'

const wallet2 = {
    color: "Grey",
    hasCash: false
};

getWalletFacts(wallet2); // => 'My wallet is Grey and does not have cash'

It's hasCash , not hascash -- JavaScript is case-sensitive.

You also need a conditional to turn the true/false values into proper English.

 function getWalletFacts(wallet) { let sentence = "my wallet is " + wallet.color + " and " + (wallet.hasCash? "has cash": "does not have cash"); return sentence; } const wallet = { color: "Black", hasCash: true }; console.log(getWalletFacts(wallet)); // => 'My wallet is Black and has cash' const wallet2 = { color: "Grey", hasCash: false }; console.log(getWalletFacts(wallet2)); // => 'My wallet is Grey and does not have cash'
