Branching Statements:
1. JavaScript supports branching statements which are used to perform different actions based on different conditions.
2. Branching is a transfer of control from the current statement to another statement or construct in the program unit.
3. A branch alters the execution sequence.

if (N< 0)
{
alert ("The value of N is Negative")
}
else
{
alert ("The value of N is Positive");
}
output: The Value of N is positive

The syntax is:
while (condition)
{
body of the loop
}

1. The switch statement begins by evaluating an expression placed between parenthesis, much likethe if statement.
2. The result compared to labels associated with case structure that follow the switch statement.
3. If the result is equal to a label, the statements in the corresponding case structure are executed.

if (condition)
{
True block;
}

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

Conditional statements execute or skip one or set of statements depending on the value of a specified conditional expression.
