Convert a list of string coords into two float lists of Lat/Longitude coordinates in JavaScript?

JavascriptWeb DevelopmentObject Oriented Programming

Let’s say the following are our coordinates −

var listOfStrings = ["10.45322,-6.8766363", "78.93664664,-9.74646646", "7888.7664664,-10.64664632"];

To convert the above into two float lists of Latitude and Longitude, use split() on the basis of comma(,) along with map().

Example

var listOfStrings = ["10.45322,-6.8766363", "78.93664664,-9.74646646", "7888.7664664,-10.64664632"];
var latitude = [];
var longitude = [];
listOfStrings.forEach(obj => obj.split(',')
.map(Number)
.forEach((value, index) => [latitude, longitude][index].push(value))
);
console.log("All positive value is latitude=")
console.log(latitude);
console.log("All negative value is longitude=")
console.log(longitude);

To run the above program, you need to use the following command −

node fileName.js.

Here, my file name is demo180.js.

Output

This will produce the following output −

PS C:\Users\Amit\javascript-code> node demo180.js
All positive value is latitude=
[ 10.45322, 78.93664664, 7888.7664664 ]
All negative value is longitude=
[ -6.8766363, -9.74646646, -10.64664632 ]
