What is the best way to construct an array within a JavaScript object on-the-fly?

Everything is functioning smoothly in the code below:

direction.route(
{
     start: '30 Baker St, Old City, YY 12345',
     end: '30 Bogus Address Ave, Fake, ZZ 12345',
     waypoints: [ "<address1>", "<address2>" ] //Using literals in an array
     
});

The issue I am encountering is the possibility of having numerous addresses stored in an array. The quantity of addresses within the array may fluctuate.

The following code would suffice, but I require the ability to dynamically construct the array within the JS object.

direction.route(
{
     start: '30 Baker St, Old City, YY 12345',
     end: '30 Bogus Address Ave, Fake, ZZ 12345',
     waypoints: [ address[0], address[1], address[2], ... ] //Using variables in an array
     
});

Answer №1

Check out my code snippet below, which utilizes the MapQuest example addresses.

var locations = [];
locations.push('366 Columbus Ave, New York, NY 10024');
locations.push('881 7th Ave, New York, NY 10019');

L.mapquest.directions().route({
  start: '350 5th Ave, New York, NY 10118',
  end: 'One Liberty Plaza, New York, NY 10006',
  waypoints: locations OR waypoints: [locations[0], locations[1]]
});

Answer №2

After much consideration, this is the solution I arrived at:

     var direction = L.mapquest.directions();
 direction.route(
 {
      start: '30 Baker St, Old City, YY 12345',
      end: '30 Bogus Address Ave, Fake, ZZ 12345',
      waypoints: locations2.slice(), //NOTE:  "Spread syntax" worked just as well here too.
      optimizeWaypoints: true
 });

I want to express my gratitude to those who helped me with this problem: Heretic-Monkey, Mr. PolyWhirl, and Guy Incognito
