Looping
Looping statements in JavaScript are used to execute the same
block of code a specified number of times.
Very often when you write code, you want the same block of code to run a
number of times. You can use looping statements in your code to do this.
In JavaScript we have the following looping statements:
- while - loops through a block of code while a condition is true
- do...while - loops through a block of code once, and then repeats the
loop while a condition is true
- for - run statements a specified number of times
while
The while statement will execute a block of code while a condition is
true..
while (condition)
{
code to be executed
} |
do...while
The do...while statement will execute a block of code once, and then it will
repeat the loop while a condition is true
do
{
code to be executed
}
while (condition) |
for
The for statement will execute a block of code a specified number of
times
for (initialization; condition; increment)
{
code to be executed
} |
