Is it in the interactive course? Please share the level number and lesson number

Please share the level number and lesson number.

Can you please share the level number?

Try this:
***
package main
import "fmt"

func main() {
var length float64 = 3.5
var width int = 4
var area int
area = int(length)*width
fmt.Println("Area is:", area)
}

Sorry for the delay.

Here is the correct code:
***
let txt1 = 'Yokozuna';
let txt2 = 'Yokohama';

if(txt1.length == txt2.length) {
console.log("Both are same");
}
***

Your answer is correct, its just that our system is a little strict. This should work:
***
let x = true;
let y = false;

// apply AND operator
console.log(x && !y)

// apply OR operator
console.log(!x || y)
***

Can you share the level number and lesson number so that I can help you.
