Peer review is the system used to assess the quality of a manuscript before it is published. Independent researchers in the relevant research area assess submitted manuscripts for originality, validity, and significance to help editors determine whether a manuscript should be published in their journal. Peer review process acts as a filter to ensure that only high-quality research is published, especially in reputable journals, by determining the validity, significance, and originality of the study. Secondly, peer review is intended to improve the quality of manuscripts that are deemed suitable for publication.
