Interview gist -- Can candidate write code?

Instructions

  • Solve all problems using JavaScript

Problems

  1. Write a function that returns an array with the first n powers of 2. Call it twoPow.

  2. Use twoPow and Array.prototype.reduce to the sum of the first 10 powers of 2.

  3. Describe this call signature:

    say("Hello")("World");  // An alert displaying, "Hello World" appears
    
  4. Implement the say function from question 3.

  5. Simplify the following code:

    if(foo !== '' || foo !== null || typeof foo !== 'undefined') {
        alert(foo);
    }
    
  6. Write a sum function that takes any number of parameters.

Yes' I'd looked at it. Classical questions, I think.
It refreshed my memory, thanks. :-)
