Given the array below:
const Array = ['Michael', 'student', 'John', 'cop', 'Julia', 'actress']
How can I transform it into an object like this?
const Object = {
Michael: student,
John: cop,
Julia: actress,
}
Is there a way to assign even index elements as keys and odd index elements as values in the resulting object?
To achieve the desired result, you can use a simple for loop that iterates through the array by two indexes at a time.
Here's an example:
const array = ['Michael', 'student', 'John', 'cop', 'Julia', 'actress'];
const output = {}
for(let i = 0; i < array.length; i+=2){
output[array[i]] = array[i+1]
}
console.log(output);const people = ['Michael', 'student', 'John', 'cop', 'Julia', 'actress'];
let data={};
people.forEach((item, index) => {
if(index % 2 === 0){
data[item] = people[index+1];
}
})
console.log(data);A method to consider is dividing the array into chunks of 2 and then transforming it into an object using Object.fromEntries.
let arr = ['Michael', 'student', 'John', 'cop', 'Julia', 'actress'];
let obj = Object.fromEntries([...Array(arr.length / 2)]
.map((_, i)=>arr.slice(i * 2, i * 2 + 2)));
