PIPELINE Developer Productivity Intermediate 1 step

Compare two text blocks line by line

When reviewing changes between file versions, a line-level diff helps focus on what actually changed. The two text blocks are separated by a line containing only '---'. Added lines are prefixed with '+', removed with '-', unchanged with a space.

What it solves

Find added, removed, and unchanged lines between two versions of a text document.
