JavaScript statements are commands to the browser. What these commands do is tell the browser what to do.
First look at the following code
<script type="text/javascript">
alert("hello!");
</script>
The example alert("hello!"); is a JavaScript statement.
The end of a line is considered the end of the statement, and a semicolon is usually added at the end ";" to indicate the end of the statement.
Look at the following piece of code, there are three statements, each with ";" at the end, execute the statements in order.
<script type="text/javascript">
document.write("I");
document.write("love");
document.write("JavaScript");
</script>
Note: Although the semicolon ";" can also be left out, we must develop a good programming habit and remember to write a semicolon at the end of the statement.
