(1) Definition:The function returns a function that returns a function called a closure (the simplest form of personal understanding).(2) Why use closures? Local variables are collected by GC after the function has been executed, and sometimes we want to access the internal variables externally, this time we use closures(3) Closures have two functions: A. Accessing variables inside functions (functions as return values) B. Save scope (function as parameter pass)1 //1. Accessing variab

Timeout call setTimeout and intermittent call setInterval, settimeintervalToday, I read the javascript advanced programming (the third edition) book and found that setTimeout is better than setInterval. SetInterval is usually used for multiple points. Now let's take a look. I learned it again. Note: parameters ------------ setTimeout contains two parameters. The first parameter is the code to be executed, and the second parameter is the time. The first parameter can be a string or a function, bu

Here's an example: Passing strings is not recommended! setinterval ("Alert (' Hello World ')", 10000); //Recommended invocation mode setinterval (function () { alert ("Hello world!"); }, 1000); Calling the SetInterval () method also returns an intermittent call ID that can be used to cancel intermittent calls at some point in the future. To cancel an intermittent call that has not yet been performed, you can use the Clerari

Read the JavaScript Advanced Programming (third Edition) today, and found that settimeout is better than setinterval, and feels that it does. Usually use setinterval more points, now or turn the idea. I learned it again. The notes are as follows:-------------------------------------------------------------------------------------------------------------------- -----------------------settimeout contains two parameters, the first parameter is the code to execute, and the second parameter is the ti

been performed, you can use the Clearinterval () method and pass in the corresponding intermittent invocation ID. Canceling an intermittent call is much more important than canceling the timeout call because, without intervening, the intermittent call will be performed until the page is unloaded. The following is a common example of using intermittent calls.varnum = 0;varmax = 10;varIntervalid =NULL;functionincrementnumber () {num++;//cancels subsequ

This is not, manual write again is a different effect appeared.To the left binary, or to the right to go relatively simple, in fact, the two algorithms are most critical: exit condition min > Max and the next binary when the subscript or superscript position to +1 or 1/// ///implementation of a recursive pure algorithm/// /// /// /// /// /// in

Longest consecutive SequenceGiven an unsorted array of integers, find the length of the longest consecutive elements sequence.For example,Given [100, 4, 200, 1, 3, 2] ,The longest consecutive elements sequence is [1, 2, 3, 4] . Return its length: 4 .Your algorithm should run in O (n) complexity.https://leetcode.com/problems/longest-consecutive-sequence/ Sort of is O (Nlogn), really did not think of how O (n).Looked at the set of Find, insert, delete is O (1).OK, O (n) +o (n) or O (n).In an

I believe everyone will understand.The time we call is Startmove (odiv,{width:200,height:200}); If necessary, add a callback function. So let's look at how the code is modified. function startmove(obj, JSON, fnend){ varmax= -;//Each call has only one timer at work (turns off

like a function in mathematics. For example, for a unary two-time function, there are X and y two unknowns, and when the value of X is determined, the value of Y is determined. In mathematics, the range of x is called the definition field , and the range of y is called the domain value.The scale in the D3 also has a defined field and a range, respectively, called Domain and ranges. The developer needs to specify the scope of domain and range so that a computational relationship can be obtained
