The Nature of Computation

5星 · 资源好评率100%

This book gives a lucid and playful explanation of the field, starting with P and NP-completeness. The authors explain why the P vs. NP problem is so fundamental, and why it is so hard to resolve. They then lead the reader through the complexity of mazes and games; optimization in theory and practice; randomized algorithms, interactive proofs, and pseudorandomness; Markov chains and phase transitions; and the outer reaches of quantum computing.

A computed property is a property in an object that is not stored as a value, but instead is dynamically computed based on other values in the object or external factors. When the property is accessed, a function is called that calculates the value of the property on the fly. Computed properties are commonly used in JavaScript frameworks like Vue.js and React to create reactive data bindings between elements in the user interface and the underlying data model. For example, a computed property could be used to calculate the total price of a shopping cart based on the prices and quantities of the items in the cart.

avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. instead, use a data or computed property based on the prop's value.
