1. Function callIn programming, a function is a name combination of a series of statements used for a certain calculation. When defining a function, you must specify the function name and write a series of program statements. Then, you can use the

It's not as simple as prototype inheritance !! Deep Exploration of prototype 1 What is prototype The prototype attribute of the object in JavaScript, which can return the reference of the Object Type prototype. This is a pretty straightforward

This article mainly introduces how to use the pdb module to debug Python program instances. This article focuses on pdb. run () function, pdb. runeval () function, pdb. runcall () function, pdb. the use of set_trace () functions and pdb debugging

In function programming, a function is regarded as a "first-class citizen ". JavaScript can be cleverly combined with functions to construct abstraction. By embedding functions, we can focus more on "What to Do functions" during software development,

Distance between two pointsMath. sqrt (Math. pow (p1. _ x-p2. _ x), 2) + Math. pow (p1. _ y-p2. _ y), 2 ))You can use this formula to calculate the distance between a point and the origin:Because the origin coordinate is (0, 0), the formula
