How to merge two tables in JavaScript and why Array.push() is 945 times faster than Array.concat()

The article on Dev.to presents a performance comparison between two methods for adding elements to arrays in JavaScript - 'Array.push' and 'Array.concat'. The author points out that 'Array.push' is a significantly faster alternative to 'Array.concat', boasting a performance increase of 945 times in some cases. This is an important takeaway, especially as we deal with larger data sets where execution time differences become substantial. The article also includes code examples that illustrate the differences in using both methods, encouraging developers to review their practices in array management and choose more efficient solutions in JavaScript. In an era where performance is critical, such information can save valuable time while building applications. Therefore, readers should pay close attention to the selection of appropriate methods to optimize their code.
