problem

strategy

we should create two kind of arrays.the first one has value of decimal numbers and the second roman numerals.we should also define 900, 400, 90,40, 9, 4 with them cause it will save us a plenty of code.we should use for loop to access each number in numbers.then in for loop we have to return value of input(num)’s roman translation.

problem explanation

In this problem we have to remove nested arrays and return whatever it was in it into a new array.

Problem explanation

In this problem you can come up with many solutions.you can solve this by hasOwnProperty() , loops , for in statements . you have to return wether predicate is truthy to all elements of a collection(first argument)


problem

Problem explanation

in this problem we are given two numbers in an array.it’s not ranged so first of all we have to range them smallest to biggest.Then we have to see whats between those numbers to do that we have to define function that arranges ,expands numbers and puts them into an array which it will return.we define variable that holds value of that function.Then we create while loop and inside of it we declare variable higherCommonNum that holds value of min and multiple numbers first multiplied by each other and the to max number.then we have to check if that higherCommonNum…
