What is the correct syntax for a 'for loop' in JavaScript ? a) for (var i = 0; i < 5; i++) b) for (i = 0; i < 5; i++) c) for (var i = 0; i < 5) d) for (var i < 5; i++)

The correct syntax for a for-loop in JavaScript is:

a) for (var i = 0; i < 5; i++) {}

Explanation:

A for loop in JavaScript follows this structure:

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

• var i = 0 initializes the loop counter.
• i < 5 is the condition that must be true for the loop to continue.
• i++ increments the counter after each iteration.

Why not the others?

• b) Missing var (declaration) → invalid in strict mode.
• c) Missing increment/decrement → infinite loop.
• d) Incorrect syntax (comparison instead of initialization) → invalid.

// Example of a working for-loop:
for (let i = 0; i < 5; i++) {
    console.log(i); // Output: 0, 1, 2, 3, 4
}
