JavaScript data types are divided into six types, namely null, undefined, boolean, string, number, and object. object is a reference type, and the other five are basic types or primitive types. We can use the typeof method to print out which type something belongs to. To compare variables of different types, you must first convert the type, which is called type conversion. Type conversion is also called implicit conversion. Implicit conversions usually occur with the operators addition, subtraction, multiplication, division, equals, and less than, greater than, etc. . typeof '11' //string typeof(11) //number '11' < 4 //falseBasic type conversion Let’s talk about addition, subtraction, multiplication and division first: 1. Add numbers to strings, and the numbers will be converted into words

Introduction: Currying is a relatively advanced application of functions, and it is not easy to understand it. So I've been thinking about how I should express myself more to make it easier for everyone to understand. After thinking about it for a long time, I decided to put aside the concept of currying and add two important but easily overlooked knowledge points. 1. Supplementary knowledge points about implicit conversion of functions. As a weakly typed language, JavaScript’s implicit conversion is very flexible and interesting. When we do not have a deep understanding of implicit conversions, we may be confused by the results of some operations, such as 4 + true = 5. When...

How to use implicit conversion? Summary of implicit conversion instance usage

Introduction: Regarding implicit conversion and explicit conversion, every language has them, and C# is certainly no exception. Commonly used situations, one is when writing arithmetic expressions, the overall data type must be consistent and the calculation accurate. For example, if there is a variable a of type int, but it is obtained by addition, subtraction, multiplication and division, then in the operation You need to consider using explicit conversion. The division operation needs to be converted to float or double, and then the result is forced to be converted to int. Another is that when passing parameters, you need to pay attention to which ones require explicit conversion, or you should also pay attention to the type when assigning values ​​to a collection. The problem.
