How can two arrays be compared in Ruby if the order is different?

Question

ruby

For example, there is an array:

foo1 = [
{name: 'Траволта', age: '15'},
{name: 'Чубайс', age: '50'}
]

foo2 = [
{ name: 'Чубайс', age: '50'},
{name: 'Траволта', age: '15'}
]

Their content is the same, but their order is different,
and if equal, == will return false. How can you do an equality check in this case?

Answer 1

You have different arrays.
[0, 1] != [1, 0].
Try to compare like this.

foo1.sort_by { |h| h.first } == foo2.sort_by { |h| h.first }
