Javascript:Convert an array to object

There are multiple ways to convert an array to object.

Using Array.reduce() Method:

Code:

var str = ["a", "b", "c", "d"]

var res = str.reduce((acc, current,index) => {

return {...acc,[index]:current}

},{})

console.log(res)

Output

{ '0': 'a', '1': 'b', '2': 'c', '3': 'd' }

Other ways are more simple.

Way 1 using spread operator:

Code:

let names =["sagar","sangram","sachin"]

let objNameSpread = {...names}

console.log(objNameSpread)

Output:

{ '0': 'sagar', '1': 'sangram', '2': 'sachin' }

Way2 using Object.assign:

Code:

let objNameAssign =Object.assign({}, names);

console.log(objNameAssign)

Output:

{ '0': 'sagar', '1': 'sangram', '2': 'sachin' }
