[typeof "this is a string", typeof "also a string"] == ['string', 'string']

Reference instead of value equality

If you want to know why arrays can’t be checked for equality, it’s because two objects must be the exact same for == to return true

For example:

[] == [] // false
x = []; x == x // true

["string", "string"] == ['string', 'string'] // false
"s" == 's' // true

oren: 
['s','a']==['s','a'] //false

oren: 
['a']==['a'] //false
