JavaScript for Loop

for (initialization; condition; increment) {
    // Code to execute
}

• Initialization: Runs once before the loop starts, typically used to declare a loop counter.
• Condition: Evaluated before each iteration. If it evaluates to true, the loop continues; if false, the loop stops.
• Increment: Executes after each iteration, usually to update the loop counter.

for (let i = 0; i < 5; i++) {
    console.log('Iteration: ' + i);
}

Iteration: 0
Iteration: 1
Iteration: 2
Iteration: 3
Iteration: 4

const fruits = ['apple', 'banana', 'cherry'];

for (let i = 0; i < fruits.length; i++) {
    console.log(fruits[i]);
}

apple
banana
cherry

let sum = 0;

for (let i = 1; i <= 10; i++) {
    sum += i;
}
console.log('Sum: ' + sum);

Sum: 55

for (let i = 0; i < 3; i++) {
    for (let j = 0; j < 2; j++) {
        console.log('i: ' + i + ', j: ' + j);
    }
}

i: 0, j: 0
i: 0, j: 1
i: 1, j: 0
i: 1, j: 1
i: 2, j: 0
i: 2, j: 1
