Shorten Given Code
Shortening Code
Optimizing and shortening code is essential for maintaining readability and efficiency, but it's crucial to do so without changing the underlying business logic. Here are some strategies and examples to help you achieve this:
1. Leverage Language Features
Example: Using Arrow Functions in JavaScript
Before:
function add(a, b) {
return a + b;
}
After:
const add = (a, b) => a + b;
2. Remove Redundant Code
Example: Simplifying Boolean Expressions in Python
Before:
def is_eligible(age):
if age >= 18:
return True
else:
return False
After:
def is_eligible(age):
return age >= 18
3. Use Built-in Functions and Libraries
Example: Summing Elements in an Array with Python
Before:
def sum_array(arr):
result = 0
for num in arr:
result += num
return result
After:
def sum_array(arr):
return sum(arr)
4. Refactor Repeated Code Blocks into Functions or Loops
Example: Processing a List of Items
Before:
print("Processing item 1...")
# process item 1
print("Processing item 2...")
# process item 2
print("Processing item 3...")
# process item 3
After:
for item in range(1, 4):
print(f"Processing item {item}...")
# process item
5. Chain Operations When Possible
Example: Chaining String Operations in JavaScript
Before:
let str = " Hello World ";
str = str.trim();
str = str.toLowerCase();
str = str.replace(" ", "-");
After:
let str = " Hello World ".trim().toLowerCase().replace(" ", "-");
Shortening code without touching the business logic involves a careful balance of refactoring, utilizing language features, and removing redundancies while ensuring that the core functionality remains intact. By applying these strategies, you can make your codebase more manageable, understandable, and efficient, thereby improving overall software quality.
