Discussion on: How would you refactor this JS function?

Assumption:

• line must is a string and length >= 1 return line
• isFirstLine is a boolean true htmlTag = h1 else htmlTag = p

const lineChecker = (line = "", isFirstLine = false) => {
    if (typeof line !== "string" || !line.length) return "<br />";

    const elementTag = isFirstLine === true ? "h1" : "p";
    return `<${elementTag}>${line}</${elementTag}>`;
};

Nice refactoring, I like the tag extraction and the input type checking!
