What Is a Slot?


A Slot is a narrow depression or perforation in a surface that receives a piece sliding in or out. The word “slot” first appears in the late 14c., but its precise origin is obscure. The word also has Old Norse roots, including slod. In 1520, the word was used to mean hollow. The word “slot” also appeared as a synonym for the word “deer,” referring to the path a bloodhound takes when following a wounded deer.

The first thing you should know about slots is that they can be used to pass reusable functionality between components. Unlike HTML elements, slots don’t have a UI and are used to pass between components and other parts of content. Similarly, a slot doesn’t have to contain HTML, enabling it to serve as a reusable component. For this reason, you should never use a “normal” component in a Slot-based application.

A hockey player can also take a shot from the slot. It is one of the best spots for a winger to put in a wrist shot with a high chance of scoring without a deflection. A high slot also allows for the winger or center to put his stick out in front of the goalie and redirect a shot. Despite the difficulty of stopping a high-speed slap shot, a well-placed one-timer from the slot is among the best shots in hockey.

Besides defining the type of slot, the user can map values to it using regular expressions. Flight numbers and codes can be matched with regex patterns. The same is true for phrases and utterances. This makes it possible to identify discrete pieces of information in a single utterance. It also helps to make it easy for the bot to interpret a particular slot and then make the appropriate decisions. This makes the input-output process faster and more effective.
