Grunt vs Jest: What are the differences?
What is Grunt? The JavaScript Task Runner. The less work you have to do when performing repetitive tasks like minification, compilation, unit testing, linting, etc, the easier your job becomes. After you've configured it, a task runner can do most of that mundane work for you—and your team—with basically zero effort.
What is Jest? Painless JavaScript Unit Testing. Jest provides you with multiple layers on top of Jasmine.
Grunt and Jest are primarily classified as "JS Build Tools / JS Task Runners" and "Javascript Testing Framework" tools respectively.
"Configuration " is the primary reason why developers consider Grunt over the competitors, whereas "Open source" was stated as the key factor in picking Jest.
Grunt and Jest are both open source tools. Jest with 26.1K GitHub stars and 3.53K forks on GitHub appears to be more popular than Grunt with 11.9K GitHub stars and 1.55K GitHub forks.
According to the StackShare community, Grunt has a broader approval, being mentioned in 794 company stacks & 421 developers stacks; compared to Jest, which is listed in 263 company stacks and 150 developer stacks.
