Javascript - The Array object

The Array object is one of the JavaScript core objects, allowing you to create and manipulate arrays.

Here is the syntax for creating an array:

var x = new Array(element1[, element2, ...]);

If no element is specified as a parameter, an empty array is created. Otherwise, it will be initialized with the values ??passed as parameters (element1,element2...).

The Array object has two characteristic properties: the input and length properties.

The following table describes the properties of the Array object.

property description constructor This property contains the constructor of the Array object. input This property allows you to search the array using a regular expression length This property contains the number of array elements. prototype Allows you to add custom properties to the object.

The following table describes the methods of the Array object.

Method description concat(array1, array2[, array3, ...]) This method allows to concatenate multiple arrays join(array) or Array.join() This method returns a string containing all the elements of the array. pop(array) or Array.pop() This method removes the last element of the array and returns its value. TArray.push(value1[, value2, ...]) This method sums up one or more elements of the array. Arraeverse() This method reverse the order of the elements in the array. Array.shift() This method removes the first element of the array. Array.slice() This method returns an array containing part of the elements of an array. Array.splice() This method adds / removes elements from an array. Array.sort() This method is used to sort the elements of an array.. Array.unshift(value1[, value2, ...]) This method returns the source code that has created the Array object. ArraoString() This method returns the string corresponding to the instruction that helped create the Array object. Array.unshift() This method allows to add one or more elements to the beginning of the table. Array.valueOf This method simply returns the value of the Array object to which it refers.
