AI-generated Key Takeaways
-
Array.tanh() computes the hyperbolic tangent of each element in an input Array.
-
The method takes a single argument, the input Array.
-
It returns a new Array containing the hyperbolic tangent of the input elements.
-
Examples demonstrate its usage in both JavaScript and Python, including plotting the results.
