Answer 1

A template is a bare bones skeleton of code, text (emails, letters etc), image layouts, project files etc... or anything that is quickly reused and readily recyclable in any of many fields and topics.

A template is efficient and stops the need to reinvent the wheel or start from scratch.

A template will have parts that the user can alter to their needs.

Sometimes, in any field, when faced with brain fog or a blank canvas, a template can inspire or steer you in the right direction to be creative and/or productive.
