Memory Leaks: Memory leaks can be terms as the memory that is not used by the application anymore and still not returned back to the pool of free memory. Different languages have different memory management system that helps them to heed the garbage memory.
Simultaneously, the roots which are left inactive will be available for use again.
If Else Error: This concept is used when you want the program to respond to every occurrence of the answer. Like for example, “==” and “=” are to misconceptions that developers normally find.
These types of typo errors must be avoided prior to moving on the final coding section. Generally, these types of test can arrive on social media.
- A variable declared within the function
- A variable declared in the parent function
- A global variable that is accessible to all
To deal with these issues, the developers are generally prescribed to avoid making unnecessary nested functions. Solving this issue will not only make your code closure free, but it will also deal with the memory allocation problem.
Whenever you are creating a new object or class, always consider associating the methods with the object's prototype instead of defining it in the object’s constructor.
Following are some points that you must be aware of:
undefined == null //true undefined === null //false typeof null //”object” should have returned null. If it’s an object, what about adding few properties typeof undefined //”undefined”
The above-mentioned bugs are a few that a JS developer generally neglects while coding for a script. These issues seem to be minor, but it causes a big loss of your memory, code structure. It also generates loopholes that make it easy to breach the code.
So, next time you write a script of code, always remember the points mentioned above. Remember that these are not the only mistakes that a code does. Instead, there are many other which should be avoided to get a bug free script.
