- Learning asynchronous programming
For fetching data, any required application calls for several internal calls to various numbers of APIs. In order to eliminate this issue, different middleware for each function can be used.
Hence, in order to aid this situation, it is good to use asynchronous APIs in the app code. In the midst, remember that for novices, the intricacies of asynchronous programming is challenging.
2.The local variables defining
Variables that are meant for defining a function are stored inside. They are categorized into two- Local Variables and Global Variables.
- Local Variables- These are the variables that are defined within themselves.
- Global Variables- These variables are used throughout the script.
When a developer calls for a function, the browser does an activity called Scope lookup. As and when the number of scope in the scope chain increases, there is also an increase in the time taken for accessing variables outside the current scope.
And this is why an engine takes more time for accessing a global variable when comparing it to the local variable. This shows that if a developer defines variables locally, there can be a visible decrease in the time taken by engine for the search purposes.
Using the local variables, the overall speed of developing applications can be boosted.
3.Small and lightweight codes
When in the process of the mobile app development timeline, ensure you are packed with the answers of questions like-
- Is there any requirement for this module?
- What is the need for this framework?
- Can you complete the task in a simpler manner?
- Is the module worthy?
Ensure you got the answers to these questions.
4.Take care of memory leakage
5.Tools for problem detection
And this is not the end, there are more tools available in the market for detecting issues and solving them precisely.
6.Implementation of event delegation
Due to the absence of Event Delegation, big web applications stop working due to the presence of many event handlers. At the same time, event delegation offers advantages such as less memory for processing, less functionality for managing along with fewer ties between code and DOM.
Less time meant for the loop further fastens the looping process. Furthermore, there are simple tricks, one of which is about storing the array’s length in a different variable compared to rewarding the length of the loop.
The user when using the app expects the page to be loaded in less than 2 seconds. And if the pages take more time, the chances of the user switching to another app or website becomes higher.
Using this trick helps in eliminating unnecessary loading and compiling JS coding. Once the page gets loaded, it becomes easier to load other functionalities for user interaction.

For solving tasks using a data structure, there are algorithms made to do so. These algorithms help in offering the following things:
- Recursive calls aversion.
- Getting the same results by doing minimal calculations.
- Clubbing calls, variables, calculations for all the regular repeated functions.
- Mathematical formulas simplification.
- Taking the leverage of processor speculative execution by creating true conditions.
- Search arrays for getting value based on another instead of switches or case statements.
Gzip is a well-known software application that is often used by clients and servers for decompression and compression.
12.Caching for performance enhancement
Memory limitations are considered a skill because it is a challenge to determine how much memory is required by the device for running a particular mobile application. At any given point, code requests the new memory reserved for the browser, where the browser’s garbage collection executes. This results in stopping the JS. And if it keeps on running in the loop, there are high chances of it making the pages slow to load.

Altogether, this is showing that JS is likely to remain the absolute choice of many tech giants in the coming years too.
