- TensorFlow is simply referring to the flow of the Tensors in the computational graph.

# TensorFlow API 兩個一開始好用的部分 ![bg right width:500](./images/tf_high.png) - low-level operation API - math operations to manipulate data - not easy - (similar to Eager Execution in TensorFlow Python API) - high-level layers API - allows you to define complex model easily - (similar to Keras in TensorFlow Python API)
a traditional JavaScript array is a tensor, a 2D array is a tensor, and a 512D array is a tensor. TensorFlow.js tensors are the embodiment of these mathematical structures that hold the accelerated signals that feed data into and out of a machine learning model.
