Today I learned about dynamic bytes in Solidity.
bytes is a dynamic array of byte values that can grow and shrink during execution.
Operations:
push β adds a new byte at the end
pop β removes the last byte
Important:
bytes supports indexing (data[0])
length changes dynamically
more gas efficient than string for low-level operations
Use cases:
data encoding
handling raw binary data
optimization in smart contracts

Today I learned about dynamic arrays in Solidity.
Dynamic arrays can grow and shrink in size during execution.
push β adds a new element at the end of the array
Example:
arr.push(100); //[10,0,30,40,90,80,5,100]
pop β removes the last element of the array
Example:
arr.pop();
Important:
push() increases the array length
pop() decreases the array length
pop() only removes the last element

Day 13 of my 30-day challenge #learningweb3
Today I learned about fixed-size arrays in Solidity.
A fixed-size array has a constant length defined at the time of declaration.
Operations:
Get β read values using index
Update β modify value at a specific index
Delete β resets value to default (0), does not remove the element
Length β returns arr.length, which cannot be increased or decreased
Example:
uint[5] public arr = [10, 20, 30, 40, 50];
The size of a fixed array is immutable, so elements cannot be added or removed.

Day 12 of my 30-day challenge #learningweb3
Today I learned about break and continue statements in Solidity.
These are used to control the flow of loops.
break β stops the loop completely
continue β skips the current iteration and moves to the next one
Example (continue):
for (uint i = 0; i < 10; i = 2) {
if(i == 6){
continue;
}
count = 5;
}
This loop skips when i = 6 and continues execution.
Example (break):
for (uint i = 0; i < 10; i = 2) {
if(i == 6){
break;
}
count = 5;
}
This loop stops completely when i becomes 6.
Important:
Loops should be used carefully in Solidity because they consume gas.

Day 11 of my 30-day challenge #learningweb3
Today I learned about loops in Solidity: for loops, while loops, and do-while loops.
Loops are used to execute a block of code multiple times based on a condition.
For loop β used when the number of iterations is known
While loop β runs as long as the condition is true
Do-while loop β runs at least once before checking the condition
Loops consume gas, so using large loops in smart contracts can be expensive and risky.
Example:
for (uint i=0; i<10; i=i 2) {
count = count 5;
}
--Loops run 5 times.
--each time add 5.
--5 Γ 5 = 25

Day 10 of my 30-day challenge #learningweb3
Today I learned about the ternary operator in Solidity.
The ternary operator is a shorter way to write if-else conditions in a single line.
Syntax:
condition ? value_if_true : value_if_false;
Example:
function check(uint _x) public pure returns (string memory) {
return _x > 100 ? "greater" : "equal or smaller";
}
This makes the code more readable and efficient for simple conditions.
Day 10 done.
