What is difference between script tag in head and body?
When scripts are included in the head they load or run before the content of the page. When you include them in the body they load or run after the preceding html. It’s usually good practice to put scripts as close to the end of the body as possible.
How does a for loop start?
The For Loop Statement 1 is executed (one time) before the execution of the code block. Statement 2 defines the condition for executing the code block. Statement 3 is executed (every time) after the code block has been executed.
Which is true of do loop?
A “Do While” loop statement runs while a logical expression is true. This means that as long as your expression stays true, your program will keep on running. Once the expression is false, your program stops running. A “Do Until” loop statement runs until a logical statement is true.
What are the 3 parts of a for loop?
Similar to a While loop, a For loop consists of three parts: the keyword For that starts the loop, the condition being tested, and the EndFor keyword that terminates the loop.
Which loop is guaranteed to execute at least one time?
do-while loopThe do-while loop is similar to the while loop, except that the test condition occurs at the end of the loop. Having the test condition at the end, guarantees that the body of the loop always executes at least one time.
Where should you include jQuery in your main HTML file?

It will only stop when the condition becomes false. … do/while – loops through a block of code once, and then repeats the loop while a specified condition is true.
What is Loop example?
A loop is used for executing a block of statements repeatedly until a particular condition is satisfied. For example, when you are displaying number from 1 to 100 you may want set the value of a variable to 1 and display it 100 times, increasing its value by 1 on each loop iteration.
Why do we use while loop?
In most computer programming languages, a while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. The while loop can be thought of as a repeating if statement.
How do you write a while loop?
With the while loop we can execute a set of statements as long as a condition is true.Print i as long as i is less than 6: i = 1. while i < 6: ... Exit the loop when i is 3: i = 1. while i < 6: ... Continue to the next iteration if i is 3: i = 0. while i < 6: ... Print a message once the condition is false: i = 1. while i < 6:
