using mozilla console
Please read the image. does it look like I am using the console window correctly? I am trying to interactively code. So, started with a very basic basic code. When I run it, i get an error. There must must be something wrong.

If you use let and not var, then you can only define this variable once. So if you run the code a second time, then Firefox complains that you redefine the variable. You would either leave out the line with let a,b,c; or enclose the code in a {} block to make it local variables.
{
let a,b,c;
a=1;b=2;c=a+b;
console.info("a+b=",c);
}
