Objective-C and JavaScript while loop

In Objective-C, you can use the while loop to repeatedly execute a block of code as long as a certain condition is true. The syntax for a while loop in Objective-C is as follows:

while (condition) {
    // code to be executed
}

Here, condition is an expression that evaluates to either true or false. The code inside the loop will continue to execute as long as the condition is true. Once the condition becomes false, the loop will exit and the program will continue with the next statement after the loop.

Similarly, in JavaScript, you can use the while loop to repeatedly execute a block of code as long as a certain condition is true. The syntax for a while loop in JavaScript is as follows:

while (condition) {
    // code to be executed
}

Again, condition is an expression that evaluates to either true or false. The code inside the loop will continue to execute as long as the condition is true. Once the condition becomes false, the loop will exit and the program will continue with the next statement after the loop.

It's important to ensure that the condition in a while loop eventually becomes false; otherwise, the loop will continue indefinitely, resulting in an infinite loop.

Example in Objective-C:

int i = 0;
while (i < 5) {
    NSLog(@"The value of i is %d", i);
    i++;
}

This code will print the value of i from 0 to 4.

Example in JavaScript:

let i = 0;
while (i < 5) {
    console.log(`The value of i is ${i}`);
    i++;
}

This code will print the value of i from 0 to 4.
