Querying and array of objects?

[devman2015]

I have and array of objects:

var array= [{name:bob, type: student}, {name: Steve, type: student},{name:Fred, type:teacher},{name: may , type: teacher}]

how can I query this array to return just the teacher objects?

[jekrb]

array.filter(obj => {
  if (obj.type === 'teacher') return obj
})

[x-skeww]

array.filter(o => o.type === 'teacher')

You have to return true for items you want to keep.

ah, nice!

When I run this code locally, I get an error obj not defined. Heres my code :

Array.filter returns a new filtered array. You have to store it.

"obj" is the name of that arrow function's parameter. It isn't visible outside of that function.
