This exercise is from the Liaoche JS tutorial. The answer is self-written.function functions are described as follows:Turn a string 13579 into a Array -- [1, 3, 5, 7, 9] and then use reduce() it to write a function that converts the string to number.The function code is as follows:' Use strict ';function String2int (s) {var arr = [];The string is converted to an array, but each element of the arrays that this method gets is still a stringfor (var i =

The first time the reduce method feels like a chicken to me, but in-depth understanding, it is a very powerful and practical way to discover the mystery.var arr = [1,2,3,4,5,6,7]; var sum = Arr.reduce ((res,now) ={//Parameter res represents the returned result, now represents the current item, and the first traversal by default res is the first item in the array, Return res + now ; }); Console.log (sum); // -The above is a very prac

Win7 Pure version of the speed of the operation is mainly determined by the system's memory, CPU and hard disk speed, of course, the CPU and hard drive after the purchase of the basic is a fixed, unless the upgrade, but the memory is acquired. The more memory will affect the system's running speed, the more memory system will become more slowly, this time need to reduce memory occupancy rate, then Win7 Pure version of how to

Introduction: Groovy's concise syntax frees developers from the typical Java™ architecture that requires code compilation but does not help express what the program really wants to achieve. In this revival of the Groovy series, groovy developer and special columnist J. Scott Hickey takes you through a series of comparisons between regular Java code and Groovy Code, showing how this exciting language frees you up so you can focus on coding Important aspect. Typically, programmers turn to program

In the development and interview, the problem of array de-weight is often favored by the beloved, the shortest code to solve the problem will make the efficiency of a greater increase. Normal array, we can use the filter method to go to the weight, details see my blog: http://www.cnblogs.com/mmykdbc/p/8422419.htmlWhen it is an array of objects, filter is dwarfed, and then with that kind of stupid one traversal method will make the work efficiency greatly reduced, this time, need to use the
