I appreciate your writing a well-thought criticism and contributing to making the article better rather than writing a meaningless troll comment. Here’s the counter-example that I should have included in the article.

const es6Function = (variable) => {
  // function logic goes here
}

The above is a function declaration, variable declaration, and a variable assignment at the same time. According to ES5 rules, since it’s a variable declaration first, it should include a semi-colon at the end. However, declaring a function this way is such common practice in ES6 code that removing the semi-colon from the end of this function is better for readability to let developers know that it’s a function and not a variable declaration.

Edit: Added examples to the article for clarity.
