Your first instruction
A program is a sequence of instructions.
The computer executes your instructions in order. console.log displays a value so you can observe what happened. Text goes inside matching quotes. The console shows the result; it does not change your code.
A recipe has separate steps. A program works the same way: start with one clear instruction.
Read the example
console.log("Hello, learner!");Check the expected output
Hello, learner!
Your challenge
Write solve(input) to return a greeting for any name: "Hello, " followed by the name and "!". Return the string instead of logging it.
Common trap
Without quotation marks, JavaScript treats a word as a variable name.
