lot of language source code and are also interested in the syntax of different languages. So let's talk about this question briefly. The first appearance is the LISP language. The LISP Language is famous for its popularity. It is a functional programming language. All statements are functions, so the function keyword is not required. The meaning of formula translation in the subsequent Fortran languageForMulaTranSlation. Since it is a formula translation language, the call of the mathematical f

Grammar Let variable1 = value1 ParametersVariable1The name of the variable to declare.Value1The initial value assigned to the variable. Noteuse the LET statement to declare a variable whose scope is limited to the block in which it is declared. You can assign a value to a variable when you declare it, or you can assign a value to a variable in a script later.Variables that use let declaration

function. means that the function may already be available before it is defined. There are two ways to define a function, one is a function definition expression and one is a function declaration statement. //function-Definition expressionsvar fns = function () { // ... };//Function declaration statementfunction Fns () { // ... }A function declaration statement is "advanced" to the top of an external script or an outer function scope, so a function declared in this manner can be called by the

If you forget to declare a variable as a local variable, the variable will be implicitly converted to a global variableFunction Swap (A,I,J) {Temp=a[i];A[I]=A[J];A[j]=temp;}Although the program does not declare the TEMP variable using VAR, execution does not go wrong, and temp is added to the global usage domain and becomes a global variable.Code that has been revisedFunction Swap (A,I,J) {var temp=a[i];A[I

pre-declare all the variables you want to use.The code snippet above performs the following behavior as follows:var"global";(function() { var myname; alert(myname); "local"; alert(myname);})();Forget the side effects of VarBecause of the two characteristics of JavaScript, it is surprisingly easy to create global variables unconsciously. First, you can even use variables without declaring them;
