Vector type: JS

Code used before fuzz:
function isASCII(str) { for (var i = 0; i < str.length; i++) { if (str.charCodeAt(i) > 127) { return false; } } return true; }

Template used:
const c = String.fromCodePoint(i) const c_upper = c.toUpperCase() if (c_upper.length > c.length && isASCII(c_upper)){ log(c) }
