Alternative Solution

Posting a different solution method to the video (and others already posted). I index the location of the first instance of the letter S in each name in the array and if it was 0 (the first letter), I added the name to the array.

const names = ['Selma', 'Ted', 'Mike', 'Sam', 'Sharon', 'Marvin'];
var sNames = [];

names.forEach(name => {
  if(name.indexOf("S") == 0) {
  sNames.push(name);
  }
})
console.log(sNames);

Returns the following in the console...

[ 'Selma', 'Sam', 'Sharon' ]

Looks good.

I tried to fit it all onto one line and came up with this. 

names.forEach( name => (name[0] === 'S') ? s.push(name) : 0);

you can make it even shorter, but its pretty unreadable

names.forEach(n=>(n[0]==='S')?s.push(n):0);
