Heres the third review
Although they are sometimes used similarly, jargon and slang are not the same. Often, they both involve an informal use of a term to communicate an idea, so there’s a bit of overlap between the two words. However, slang is simply informal language, whereas jargon is specific to a group of people.
For example, most English speakers know that “cool” is slang for something that’s good, but only a plumber would know that “brass” is plumbing jargon for a faucet or fixture.
