console.log() and var_dump() are the most important tools used by developers to understand their code and how it works, especially when looking for errors and debugging them, they also help when working with APIs to understand the structure of their response.
The Developer's Lens: Debugging and Diagnosing
On the other hand, PHP’s var_dump() is also a built-in function that offers similar features to console.log() but gives a comprehensive view of values such as data type.
Understanding Execution Flow
One of the most important parts of coding or skill needed by every developer is understanding the flow of execution and this is a very crucial step to identify the root causes of errors. console.log() and var_dump() play an important role in this purpose.
This is done mostly by placing these functions along an execution flow between methods and statements to understand how variables are manipulated and how methods are being executed and what kind of response they produce.
Apart from Debugging, console.log() and var_dump() also play a role in performance optimization. By using console.log() and var_dump(), developers can measure the efficiency of their code, and identify resource-intensive processes that lead to bottlenecks.
Learning and Understanding
console.log() and var_dump() aren't just for debugging; they also help developers understand and learn the behaviour of their code, which leads to the optimization and brainstorming of new ideas.
