removed from the array, and if the second argument is omitted, all elements are deleted from the starting point to the end of the array. Splice () returns an array of deleted elements that return an empty array if no elements are deleted.var a=[1,2,3,4,5,6,7,8];a.splice (4); // return [5,6,7,8],a to [1,2,3,4] // return [2,3],a to [1,4] // return [4],a to [1]Splice () The first two parameters specify the array elements that need to be deleted, followed by any parameters that specify the eleme

the function that declares it and in any function nested within the body of the function. So in a function body, no matter where the variable is declared or even before it is declared, it can be used (without prompting for an error), but only after it has been declared and assigned, can it use the value assigned to it correctly. Therefore, in general, a good habit is to put the local variables to be declared in the function body at the top of the function body. var scope= "Global"; function f (

set at the beginning of the instance object creation. objects created from direct amounts of objects use Object.prototype as their prototypes, and objects created by new use the prototype property of the constructor as prototypes. Objects created by Object.create () use the first parameter as a prototype.To detect whether an object is a prototype of another object (or in a prototype chain), use the isPrototypeOf () method.var p={x:1}; // defining a prototype object var o=object.create (p);
