Support for constants (also known as immutable variables), i.e., variables which cannot be re-assigned new content. Notice: this only makes the variable itself immutable, not its assigned content (for instance, in case the content is an object, this means the object itself can still be altered) Form data can be serialized by both jQuery and JavaScript but, the major difference between them is that, jQuery's serialize() method returns form field values in top down sequence whereas, serialize JavaScript returns it in bottom up sequence. Here in this example you will see that contact number field's value will be shown up first in the query string which is the last field of the form. Some time ago, I needed to use a JavaScript hashmap.

In order words, I needed to search through my object collection using a unique key value {{:name}} Render the name property of the current data item {{if showNickname && nickname}}... {{/ if}}An {{if}} tag: Render the block content only if the expression. jQuery Migrate 3.3.0 or newer logs warnings for all input that's affected by this change, regardless of whether the jQuery.UNSAFE_restoreLegacyHtmlPrefilter() method was called or not.Note: if you overwrite jQuery.htmlPrefilter manually, you'll lose those warnings!.
