ts-jest vs typescript compiler

[k-rajat19]

hi,
I just want to ask
how ts-jest is different from typescript complier tsc?
both can compile my jest-test with type checking.

ts-jest is a Jest transformer which uses TypeScript compiler API to compile ts to js on the fly which Jest can use to run.

tsc is a TypeScript command. If you use tsc, you will need to point Jest to run against the compiled output while ts-jest automatically gives Jest what Jest needs.
