JavaScript JavaScript Array Iteration Methods Array Iteration Examples Using forEach()

Position of things inside array

const places=['Melbourene','sydney',,'Merryland','Queensland','Manly','Australia']; let newArray=[]; places.forEach(place=>{ if (place.charAt(2)==='M'){ newArray.push(place); } });

console.log(newArray);

This code does not work.Its almost same as i am trying to make newArray starting from Alphabet M.But, when i change the position of the array to 0 that is first one it works again as Melbourne is at the first

if (place.charAt(0)==='M')

Why does this happen???????

So what the charAt function refers to is the nth character (zero based indexing) of location which is being called in the forEach method. 

var places = ['Melbourene','sydney','Merryland','Queensland','Manly','Australia']; 
var newArray = []; 

places.forEach(place =>{ if (place.charAt(0)==='M'){
  newArray.push(place); 
  console.log(place.charAt(1), "Is the 2nd char in ", place);

} });

console.log(newArray);

I added a console log to hopefully convey the point of what the charAt method is doing. The method is implemented on the string in this case. In your case, I don't think any of the locations have "M" as their 3rd character.
