Introduction To JavaScript
JavaScript is a lightweight, cross-platform, and interpreted scripting language. It is well-known for the development of web pages, many non-browser environments also use it. JavaScript can be used for Client-side developments as well as Server-side developments. JavaScript contains a standard library of objects, like Array, Date, and Math, and a core set of language elements like operators, control structures, and statements.
Advantages of JavaScript
The merits of using JavaScript are −
- Less server interaction − You can validate user input before sending the page off to the server. This saves server traffic, which means less load on your server.
- Immediate feedback to the visitors − They don’t have to wait for a page reload to see if they have forgotten to enter something.
- Increased interactivity − You can create interfaces that react when the user hovers over them with a mouse or activates them via the keyboard.
- Richer interfaces − You can use JavaScript to include such items as drag-and-drop components and sliders to give a Rich Interface to your site visitors.

Day 3: Throw – Hacker Rank Solution
Problem:
Objective
In this challenge, we practice using throw and catch statements to work with custom error messages.
Task
Complete the isPositive function below. It has one integer parameter, . If the value of is positive, it must return the string YES
. Otherwise, it must throw an Error according to the following rules:
- If is , throw an Error with
Zero Error
. - If is negative, throw an Error with
Negative Error
.
Input Format
Locked stub code in the editor reads the following input from stdin and passes each value of to the function as an argument:
The first line is an integer, , denoting the number of times the function will be called with some .
Each line of the subsequent lines contains an integer denoting some .
Constraints
Output Format
If the value of is positive, the function must return the string YES
. Otherwise, it must throw an Error according to the following rules:
- If is , throw an Error with
Zero Error
. - If is negative, throw an Error with
Negative Error
.
Sample Input 0
3 1 2 3
Sample Output 0
YES YES YES
Explanation 0
Each of the given values is positive, so we return YES
each time. The value returned during each function call is printed on a new line by locked stub code in the editor.
Sample Input 1
3 2 0 6
Sample Output 1
YES Zero Error YES
Explanation 1
Locked stub code in the editor makes the following three calls to the isPositive function:
isPositive(2)
: This returnsYES
because is positive.isPositive(0)
: Because , we throw an Error withZero Error
. This is caught by the locked stub code and the value of its is printed.isPositive(6)
: This returnsYES
because is positive.
Sample Input 2
2 -1 20
Sample Output 2
Negative Error YES
Explanation 2
Locked stub code in the editor makes the following two calls to the isPositive function:
isPositive(-1)
: Because , we throw an Error withNegative Error
. This is caught by the locked stub code and the value of its is printed.isPositive(20)
: This returnsYES
because is positive.

function isPositive(a) { if (a === 0) { throw Error("Zero Error"); } if (a < 0) { throw Error("Negative Error"); } return "YES"; }
