Reserved Keywords

Here is a full list of all the JavaScript reserved keywords. Variables and functions shouldn't be named after the reserved keywords as this will result in errors leading to non execution of your codes. Infact, use reserved keywords in cases where they are used only and in strings if a string contains them.

Some of these reserved keywords have no use in JavaScript yet but were reserved in case of whatever add on or changes, JavaScript may experience in the future. Implications Of Using Reserved Keywords
<script>
var delete = 1;
alert(delete);
