The following table is a set of statements and keywords that can be used in the script.

| A |
| Executing different processes based on different conditions. |
| Terminates execution of the current iteration in a loop and then execute the next iteration in a loop. |
| Terminates the execution of a loop entirely. |
| Ends function execution and the function caller will return specifies a value. |

Example for if
…else
:
In this example, if A
equals 1, assign 5 to A
. If A
equals 2, assign 10 to A
. If A
does not equal 1 or 2, assign 0 to A
.
A = 1;
if (A == 1) {
A = 5;
} else if (A == 2) {
A = 10;
} else {
A = 0;
}

Example forwhile
:
In this example, 0 is set as the initial value for variable A
. When A
is less than 10, A
will increment by 1 every execution until A
equals 10. Once A
equals 10, the while
loop will end.
...
while (A < 10) {
A = A + 1;
}
Example for do
...while
:
In this example, 0 is set as the initial value for variable A
. The do
statement will first be executed and increment A
by 1 every execution until equal to 10. Once A
equals 10, the do
...while
loop will end.
A = 0;
do {
A = A + 1;
} while (A < 10);
Example for for
In this statement, all expressions for the initialization, the decision-making, and the post-loop process are described in a single statement line.
The following example displays the WHILE statement example shown above but uses the FOR statement instead.
for (i = 1; i < 11; i = i+1) {
A = i;
console.log(A);
}
For (A=0; A<10; A=A+1) { // Write the loop statement. } |
