Do you bother to code optimization
A lot of people aspire to be a developer but do they actually know in what depth they should understand development, it can just removing the dead code or understanding the allocation of registers for a particular code to be executed. We at stimulus believe in developing any website or app with all the code optimization in the background which eventually helps in making the websites or apps faster.
What is code optimization?
Code optimization, as the name indicates can be explained as the method that is used for the modification of codes in order to improve the efficiency and quality of the code. As a result of optimization, a program may become lesser in size, consume lesser memory, execute more rapidly, or performs fewer operations (input/output). An optimized program should possess exactly the same outputs and side effects as that of its non-optimized program. However, the benefits are given more weight in comparison to alteration in program behavior.
If we follow the basics tutorials for code optimization on well-established platform Tutorialspoints, code optimizing process must follow the three rules given below:
- The output code must not, in any way, change the meaning of the program.
- Optimization should increase the speed of the program and if possible, the program should demand fewer resources.
- Optimization should itself be fast and should not delay the overall compiling process.
Types of code optimization
1.High level, Intermediate level, low-level level optimization
2.Machine dependent and machine-independent optimization
Tips for code optimization / process optimization-
- Block Identification
Each program has some blocks in it and once the blocks are identified, it makes the process of data flow easier, and also the functionalities are easily distinguishable.
- Control flow graph
The control flow graph for the program can help in how the flow of code is supposed to work and hence coding can be done accordingly.
- Loop optimization
Move code whose effect is independent of the loop’s iteration outside the loop.
- Dead code elimination
Remove the variable whose value is no longer in use, this way you can free space for the next variable.
Replace function call with function body and hence it will take less time.
- Partial Evaluation
Statically evaluate those components of a program that can be evaluated
- Strength Reduction
Replace expensive operations with equivalent cheaper (more efficient) ones.
Optimization is a process, not a product
Code optimization is a never-ending process and you need to be careful that the optimization should not hinder the flow of the program. Code optimization and understanding of the same comes with the experience of coding and hence never feels that you have lagged behind. Reading and following the practices used by successful coders helps a lot and also acts as a building block in your career. We at Stimulus make sure that we give our developers time to understand the process so that the deliverables are best in every possible way.
