What will happen with for(i=0;;)

for(i=0;;){
    console.log("Hello world")
}

The code block that is provided is a JavaScript loop that continuously prints “Hello world“. Let’s break it down:

1. We initialise the variable i to 0 using the statement i = 0.
2. The loop condition is empty, which means there is no specified condition for the loop to terminate. As a result, the loop evaluates to true by default, creating an infinite loop. We denote this with for(;;).
3. The loop body consists of a single statement: console.log("Hello world"). This statement logs the string “Hello world” to the console, which is typically an output area provided by the browser or the JavaScript environment.
4. Since we do not explicitly update or increment the loop variable i within the loop body, the value of i remains unchanged. Consequently, the loop continues to execute indefinitely, repeatedly logging “Hello world” to the console.

This type of infinite loop is generally not desirable in most practical scenarios as it can cause the program to hang or become unresponsive since it never breaks out of the loop. To avoid this, it is essential to include a condition within the loop that eventually evaluates to false, allowing the loop to terminate.
