Precautions in using return statement

JavaScript ends automatically on the last line of code by default.

The following two instances return the same result (one with a semicolon and one without):

Example 1

Function myFunction (a) {

Var power = 10

Return a * power

}

Example 2

Function myFunction (a) {

Var power = 10

Return a * power

}

JavaScript can also use multiple lines to end a statement.

The following example returns the same result:

Example 3

Function myFunction (a) {

Var

Power = 10

Return a * power

}

However, the following instance result returns undefined:

Example 4

Function myFunction (a) {

Var

Power = 10

Return

A * power

}
