Break Statement	Continue Statement
The break statement will terminate the loop irrespective of the condition.	The continue statement will skip back to the loop condition check.
The break statement is executed and the loop is terminated.	When the continue statement is executed, the current iteration of the enclosing loop is terminated, and the next iteration begins.

switch (expression)
{
case label 1:
statements 1;
break;
case label 2;
statements2;
break;
case labeln;
statements - N;
break;
default:
statements;
}

There are different branching statements. They are :
1. if statement
2. if... else statement
3. else if statement
4. switch statement

In JavaScript there are times when the same portion of code needs to be executed many times with slightly different values is called Loops. JavaScript supports three kinds of looping statements.
They are
for loop
while loop
do .. while loop

if (expression)
{
// Execute code block #1
}
else if (expression)
{
// Execute code block #2
}
else if (expression)
{
// Execute code block #3
}
else
{
// if all else fails, execute block #4
}

The for loop is a very rigid structure that loops for a pre-set number of times. In JavaScript for structure is very flexible and is very commonly used. The syntax of the for loop looks like the following:
for(initialization; condition; increment/decrement)
{
Body of the loop;
}
The for structure consist of parts each separated by semicolon. They are,
1. The first part of the loop initialize a variable which is also called as control variable. In most case the control variable is declared as well as initialized.
2. The second part is the conditional statement that determines how many times the loop will be iterated.
3. The third and final part determines how the value of control variable is changed (Incremented/ Decremented)
