so I have an array ['banana', 'apple', 'grape']
how can I transform into the object below?
{
banana: {
apple: {
grape: { }
}
}
}
You can use reduceRight() to recursively build the result object:
const data = ['banana', 'apple', 'grape'];
const result = data.reduceRight((a, v) => ({ [v]: a }), {});
console.log(result);You can simply loop over given value and keep track of previously added object
let arr = ['banana', 'apple', 'grape']
function createObj(arr) {
let obj = {}
let temp = obj
for (let key of arr) {
temp[key] = {}
temp = temp[key]
}
return obj
}
console.log(createObj(arr))
