function toText(arr) {
    const recur = ({Item, Children}) => Item?.Name + 
        (Children?.length ? "\n" + Children.map(recur).map((text, i, {length}) =>
            i < length-1 ? "├──" + text.replace(/\n/g, "\n│  ")
                         : "└──" + text.replace(/\n/g, "\n   ")
        ).join("\n") : "")
    return arr.map(recur).join("\n");
}

// Example:
let arr = [{
    "Item": {
        "Name": "A"
    },
    "Children": [
    ]
}, {
    "Item": {
        "Name": "B"
    },
    "Children": [{
        "Item": {
           "Name": "BA"
        },
        "Children": [{
            "Item": {
                "Name": "BAA"
            },
            "Children": [{
                "Item": {
                    "Name": "BAAA"
                }
            }, {
                "Item": {
                    "Name": "BAAB"
                }
            }, {
                "Item": {
                    "Name": "BAAC"
                }
            }]
        }, {
            "Item": {
                "Name": "BAB"
            },
            "Children": [{
                "Item": {
                    "Name": "BABA"
                }
            }]
       }]
    }, {
        "Item":{
            "Name": "BB"
        }
    }]
}];
console.log(toText(arr));
