In this HackerRank Day 0: Data Types 10 days of javascript problem solution there are Variables named firstInteger, firstDecimal, and firstString are declared for you in the editor below. You must use the  operator to perform the following sequence of operations:

  1. Convert secondInteger to an integer (Number type), then sum it with firstInteger and print the result on a new line using console.log.
  2. Convert secondDecimal to a floating-point number (Number type), then sum it with firstDecimal and print the result on a new line using console.log.
  3. Print the concatenation of firstString and secondString on a new line using console.log. Note that firstString must be printed first.

HackerRank Day 0: Data Types problem solution

Problem solution in JavaScript programming.

/**
*   The variables 'firstInteger', 'firstDecimal', and 'firstString' are declared for you -- do not modify them.
*   Print three lines:
*   1. The sum of 'firstInteger' and the Number representation of 'secondInteger'.
*   2. The sum of 'firstDecimal' and the Number representation of 'secondDecimal'.
*   3. The concatenation of 'firstString' and 'secondString' ('firstString' must be first).
*
*	Parameter(s):
*   secondInteger - The string representation of an integer.
*   secondDecimal - The string representation of a floating-point number.
*   secondString - A string consisting of one or more space-separated words.
