JavaScript JavaScript Basics (Retired) Storing and Tracking Information with Variables The Variable Challenge Solution

Posted by stefanides

My code is working, but i don't store sentence in variable

var adjective = prompt("Lorem"); var verb = prompt("Ipsum"); var noun = prompt("Dolor");

alert("Done");

document.write("This " + adjective + " is a dummy" + verb + " text" + noun);

Everything is working, why should i put sentence into a new variable and add 2 lines of new code ( += "text" like this one) if i can run everything in one line of code in document.write?

Thank you!

Hello Denis Stefanides , 

                       To make it into a better way to write this program - try like our professor said - I did my very first own code as he taught. Split up your code to make it easy  and understandable -> It's awesome. Check ma code - i hope it helps

console.log("Begin Program");

var name = prompt("What is your name?");

var age = prompt("What is your age?");

var ambition = prompt("What is your ambition?");

var food = prompt("What is your favorite food?");

var future = prompt("Where you wanna see yourself in the future?");

alert("Are you sure that you've finished with your story?");

var result = " My name is " + name;

result += " and I'm" + age + "years old.";

result += " My ambition is to become a" + ambition;

result += " My favorite food is " + food;

result += " and I want to see myself as " + future.toUpperCase();

document.write(result);

console.log("End Program");

Siddharth GS, This is a great example. I had the same question as Denis. I also used numerous variables in my challenge but put it all into the document.write function. I can see now how clear this is to understand the code when it is structured this way. This would seem to make edits easier. Thanks for taking the time to show your example. Helpful.

The short answer: you don't need to! The only reason you might want to do that is for clarity, so that the sentence is constructed outside of the document.write function, and then supplied as an argument to it. Part of becoming a good programmer is writing code that is easy for other developers to read and understand.

Hey Denis, A lot of the time the teachers are teaching the fundamentals (eg. variable concatenation). Sometimes you may need to store your output in a variable, other times you can just dump it out as you've suggested.

The other thing about coding is that there are usually many ways to achieve the same result. The only way to learn these ways is to go through them, you can then see what works best for your circumstance or taste.
