Answer 1

You can split the array at the spaces and assign them to variables like so, refer here to know more about destructuring

 const data = '["12.8651929 77.576346 946.1199908085856 0.0"]'; const [latitude, longitude, altitude, speed] = JSON.parse(data)[0].split(' '); console.log(latitude, longitude, altitude, speed);

Answer 2

You can use split method in js to get the array like this

const str = ['13.8650839 78.5766843 867.699951171875 0.0'];

const words = str[0].split(' ')
console.log(words);

Now you get ouptut like this

Array ["13.8650839", "78.5766843", "867.699951171875", "0.0"]

Now you can extract easily you data using array index..
