If you’re given a nested object, how do you flatten that object with recursion in JavaScript? For example, we have this object. And we want to flatten it into the following form How would you do it? Solution To solve this solution, you need a nested function. The first function is to define a variable … Read more
If you’re given an integer n, how do you print the Fibonacci sequence up to n in JavaScript? First of all, since there are varying understanding of Fibonacci sequence, in this case we’ll assume that the 0th number is 0, 1st number is 1 and the next numbers are the sum of the previous 2 … Read more
If you’re given an integer n, how would you get the nth number of Fibonacci sequence in JavaScript? I’ll show you 2 ways to do it, a recursive and an iterative solution. For this case, we’ll assume the first Fibonacci number is 1, since there are cases where the first Fibonacci number is 0. So, … Read more
