for loop syntax javascript

A For loop is used in Javascript, which can have a significant impact on performance when there are many data records to loop. At this point we can consider expanding the for loop, where the Duff device (Duff device) will be used.Let's start with a small example, with a For loop:function Process (data) {Htmlstr+ = data

去6元钱。daySum -= 6; 由此还隐含了一个问题，就是如果不是5的倍数天的话，钱要累加daySum += dayMoney;F:因为不知道是多少天，所以我用死循环，一旦超过100元我就退出循环。*/class WhileDemo {public static void main(String[] args) {//每天要存储的钱是2.5元double dayMoney = 2.5;//存钱的初始化值是0double daySum = 0;//从第一天开始存储int dayCount = 1;//最终存储不小于100就不存储了int result = 100;//因为不知道是多少天，所以我用死循环，while(true) {//累加钱daySum += dayMoney;//一旦超过100元我就退出循环。if(daySum >= result) {System.out.println("共花了"+dayCount+"天存储了100元");break;}if(dayCount%5 == 0) {//花去6元钱daySum -= 6;System.out.println("第"+d

code, such as the loop structure or the conditional statement with the structure selected, does not need to be followed by a semicolon; otherwise, the execution path of the original structure will be changed.For example, if (a = 1): After a semicolon is added, the content following the Condition Statement is executed no matter whether the value of a is 1. The condition test fails.V. JavaScript placementJav

event Loop, but its operating mechanism is different from the browser environment. Take a look at the schematic below (author @busyrich). According to the above figure, the operating mechanism of Node.js is as follows. (1) The V8 engine parses JavaScript scripts.(2) The parsed code calls the node API.(3) The LIBUV Library is responsible for the execution of the node API. It assigns different tasks to

Query syntax allowsProgramLogical expressions are converted from imperative to declarative ". The query syntax defines the desired result and submits the specific implementation to other special implementations.You can use the query syntax (or the method syntax that implements the query expression mode) to clearly expr
