Day 0: Data Types(2) || hackerrank || 10 days of javascript || programming_info

Objective

Today, we're discussing data types. Check out the attached tutorial for more details.

Task

Variables named , and  are declared for you in the editor below. You must use the  operator to perform the following sequence of operations:

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

Input Format

Data TypeParameterDescription
stringThe string representation of an integer you must sum with .
stringThe string representation of a floating-point number you must sum with .
stringA string of one or more space-separated words you must append to .

Output Format

Print the following three lines of output:

  1. On the first line, print the sum of  and the integer representation of .
  2. On the second line, print the sum of  and the floating-point representation of .
  3. On the third line, print  concatenated with . You must print  before .

Sample Input 0

12
4.32
is the best place to learn and practice coding!

Sample Output 0

16
8.32
HackerRank is the best place to learn and practice coding!

Explanation 0

When we sum the integers  and , we get the integer .
When we sum the floating-point numbers  and , we get . When we concatenate HackerRank with is the best place to learn and practice coding!, we get HackerRank is the best place to learn and practice coding!.

You will not pass this challenge if you attempt to assign the Sample Case values to your variables instead of following the instructions above.

Now here's the solution:-

code snippet:

function performOperation(secondInteger, secondDecimal, secondString) {
    const firstInteger = 4;
    const firstDecimal = 4.0;
    const firstString = 'HackerRank ';
            // of the 'firstInteger' and 'secondInteger' 
            // (converted to a Number type) on a new line.
    console.log(firstInteger+parseInt(secondInteger)) ;
            // Write code that uses console.log to print the sum of 'firstDecimal' 
            //and 'secondDecimal' (converted to a Number type) on a new line.
    console.log(firstDecimal+parseFloat(secondDecimal));
            // Write code that uses console.log to print the concatenation of
            // 'firstString' and 'secondString' on a new line. The
            // variable 'firstString' must be printed first.
     console.log(firstString+secondString );
