Key Concepts
- Array: An ordered collection of elements.
- Array Iteration: The process of visiting each element in an array.
- Looping: A control structure that repeatedly executes a block of code.
- Array Elements: The individual values stored in an array.
Practical Steps
- Define the Array: Declare and initialize an array with the desired elements.
- Use a
for
Loop: Use a for
loop to iterate through the array.
- Access Array Elements: Use the loop variable as an index to access each element in the array.
- Perform Operations: Within the loop, perform any desired operations on the array elements.
JavaScript Example
// Define an array
const numbers = [1, 2, 3, 4, 5];
// Iterate through the array using a for loop
for (let i = 0; i < numbers.length; i++) {
// Access and print the current element
console.log(numbers[i]);
}
