Understanding JavaScript output is crucial for debugging and code comprehension.

• JavaScript uses dynamic typing, meaning variables can hold any data type.

• Example: let x = 5; x = 'Hello'; // x is now a string.

• Functions can return different types based on conditions.

• Example: function test() { return true ? 1 : 'string'; } // returns 1.

• Console.log() is commonly used to display output in JavaScript.

A simple Node.js Todo app with endpoints to add, update, and retrieve tasks.

• Implement POST /todos to add a new todo item.

• Implement PUT /todos/:id to update an existing todo item.

Check if array can be made strictly increasing by modifying at most 2 elements.

• Iterate through the array and check if each element is greater than the previous one.

• If there are more than 2 elements that need to be modified, return false.

• Examples: ['1', '2', '3'] -> true, ['1', '3', '2', '4'] -> true, ['1', '1', '2', '3'] -> false

Divide 1000 servers into 100 groups to check if streams are strictly increasing in parallel

• Divide the 1000 servers into 100 groups of 10 servers each

• Assign each group of servers to a separate processing unit for parallel checking

• Check if the stream on each server within the group is strictly increasing

• Combine the results from all groups to determine if all streams are strictly increasing

Use remote backend in Terraform to manage state file in a common place.

Freestyle pipeline allows more flexibility in defining build steps compared to normal pipeline. Build success can be checked by examining the build status or logs.

• Freestyle pipeline allows users to define build steps manually, while normal pipeline follows a predefined structure.

• In freestyle pipeline, build steps can be configured using GUI, whereas normal pipeline uses a script-like syntax.

• To check if a build is succe...read more
