Day 0: Hello World
Use
console.log()
to print Hello, World! on a new line in the console, which is also known as stdout or standard output. The code for this portion of the task is already provided in the editor.Use
console.log()
to print the contents ofparameterVariable
(i.e., the argument passed to main).
/**
* A line of code that prints "Hello, World!" on a new line is provided in the editor.
* Write a second line of code that prints the contents of 'parameterVariable' on a new line.
*
* Parameter:
* parameterVariable - A string of text.
**/
function greeting(parameterVariable) {
// This line prints 'Hello, World!' to the console:
console.log('Hello, World!');
// Write a line of code that prints parameterVariable to stdout using console.log:
console.log(parameterVariable);
}
Day 0: Data Types
- The function receives an integer, a float, and a string
- The function has a constant integer of 4
- The function has a constant float of 4.0
- The function has a constant string of “HackerRank”
- Console log the sum of the constant integer and the integer received
- Console log the sum of the constant float by the float received
- Console lot the constant string following the string received on one line
/**
* 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.
