JavaScript JavaScript Basics Making Decisions in Your Code with Conditional Statements Boolean Values

Why is this method better than a just asking if their guess was 6 for the conditional statement?

it seems like it would be a lot easier to do

let guess = prompt("Guess a number 1 to 10");

if (guess === 6) {

console.log("thats correct")

}

else {

console.log("thats incorrect")

}

is there a reason storing the value as a boolean is better here? or is this maybe just a dumbed down example for understanding the concept and it will be applied better in the future?

You're right that the example is to illustrate working with booleans and isn't necessarily the best way to handle a particular task.

However, you couldn't use the type-sensitive equality operator to match a string with a number. But you could do:

if (guess === "6") {  // match string with string
// ...or...
if (+guess === 6) {   // match number with number
// ...or...
if (guess == 6) {     // use normal (type coercing) comparison
