Type checking of array index value in Ruby -

in javascript if want type checking of array index can this:

var array = [1,2,3,4,"the monster green lagoon"]  (i=0;  < array.length;  i++) {      if (typeof(array[i]) === 'number')      {     console.log("yes these numbers");      }      else        {     console.log("index number " + + " " +  array[i] +": no not number");      }  } 

in ruby don't understand how this. i'm trying type check against integers. understand in ruby world it's considered etiquette use each method basic looping this:

array = [1, 2, 3, 4, 5, 6] array.each { |x| puts x } 

the part i'm confused syntax foreign , i'm unclear logic goes. haven't gotten actual type checking yet read compare against integer type thus:

if array[i] == integer 

thank you.

a = [1,2,3,4,5] a.all? { |x| x.is_a? integer }
