You gotta make programming fun once in a while. Why not have a banana!
('b'+'a'+ +'π'+'a').toUpperCase();
// BANANA
WTF! π
Depending on the context, +
in JavaScript will function as the unary operator to convert an operand into a number. The first plus sign is used to concatenate the "b" and "a" strings while the third is used to convert π to a Number type - and this returns NaN
. Add a trailing "a", use another +
to concatenate "ba" + NaN + "a"
, set it to all caps, and we get BANANA
!

See what this returns in the Chrome console!
const p1 = (+'π¦'+'a'+ +'π¨'+'a').repeat(2);
const str = window.BatteryManager.toString();
const p2 = str.slice(9, 19).replace('tery', '');
console.log(`${p1} ${p2.toUpperCase()}!`);
