A journal article is a type of scholarly publication where experts share the latest research, insights, and developments in their field. These articles are typically published on a regular schedule, such as monthly, quarterly, or annually.
Peer-reviewed journal articles are written by experts and then evaluated by other specialists in the same field. This process ensures that the content is credible and reliable, making peer-reviewed articles more authoritative than those that haven't undergone this scrutiny.
Journal articles often have a specific writing style that can be more complex and challenging to read compared to other sources.
