JavaScript is the language for developing dynamic websites. Previously, several guidelines were published about how to write efficient JavaScript code. Our research focuses on whether programmers should still adhere to these guidelines or can they rely on the state-of-the-art JavaScript execution engines to achieve good performance results. We present the experiments where we validate programming guidelines for JavaScript execution performance across multiple state-of-the-art web browsers. We present our observations, and conclude that the importance of guidelines does not decrease with the introduction of new JavaScript technologies (such as JIT).
