How To Make An IF Statement

To make an If statement, you must first have a script element. It should look like this:

<script>

</script>

Next, write "if () {", add two lines, and put a condition inside "()". Put code inside of the second line, and a "}" in the third.

<script>
 if (variable == 3) {
 alert("TRUE");
 }
</script>

You can also add "else" to the "}" line, and repeat the previous steps to execute different code if the condition is false.

<script>
 if (variable == 3) {
 alert("TRUE");
 } else {
 alert("FALSE");
 }
</script>

Finally, you can also add "else if" or "elif", as well as another condition. This allows you to have multiple outcomes. You can have one for if condition 1 succeeds, for if condition 1 fails but condition 2 succeeds, for if 1 and 2 fail but 3 succeeds, etc.

<script>
 if (variable == 1) {
 alert("one");
 } else if (variable == 2) {
 alert("Two");
 } else {
 alert("Not one or two");
 }
</script>
