Javascript iterate Json Array to get values

Question

I have a below JavaScript

var arr = [];
arr.push({0:\'Zero\'});
arr.push({1:\'One\'});
console.log(Object.keys(arr));
console.log(Object.values(arr)); //Not          


        

Answer 1

Here you're pushing Objects inside array so you need to access them using index.

var arr = [];
arr.push({0:'Zero'})
arr.push({1:'One'})

let values = arr.map((e,index)=> arr[index][Object.keys(e)[0]])
console.log(values)

On side note: Both of your console is not working change the keys to anything else than 0 and 1 and see the output. In case of array Object.keys will return the index of array which 0, 1 and so on

var arr = [];
arr.push({0:'Zero'})
arr.push({10:'One'})

console.log(Object.keys(arr))

Probably this is what you wanted to achieve. If this is the case than you need to use {} ( Object ) instead of [] ( Array )

var arr = {};
arr['0'] = 'Zero';
arr['1'] = 'One';

console.log(Object.keys(arr));
console.log(Object.values(arr))
