The map() function of the TypedArray object accepts the name of a function and calls it on every element of the typed array and returns the results.SyntaxIts Syntax is as followstypedArray.map()Example Live Demo    JavaScript Array every Method           var int32View = new Int32Array([11, 5, 13, 4, 15, 3, 17, 2, 19, 8 ]);       document.write("Contents of the typed array: "+int32View);       document.write("");       function square(ele) {          return ele*ele;       }    var result = int32View.map(square);    document.write("Specified element occurred at the index: "+result); OutputContents of the typed array: 11,5,13,4,15,3,17,2,19,8 Specified element occurred at the index: 121,25,169,16,225,9,289,4,361,64

The lastIndexOf() function of the TypedArray object accepts a value and verifies whether the typed array contains the specified element. If so, this function returns the index of the array at which the specified element found, if the element occurred multiple timed this function returns the last index among them. If the array doesn’t contain the specified element the indexOf() function returns -1.SyntaxIts Syntax is as followstypedArray.lastIndexOf(50)Example Live Demo    JavaScript Array every Method           var int32View = new Int32Array([21, 19, 65, 21, 14, 66, 87, 55, 66, 97, 66 ]);       ...

The keys() function of typedArray object is similar to entries but, it returns an iterator object containing the indices of the typed array.SyntaxIts Syntax is as followstypedArray.keys()Example Live Demo    JavaScript Array every Method           var int32View = new Int32Array([21, 64, 89, 65, 33, 66, 87, 55]);       document.write("Contents of the typed array: "+int32View);       document.write("");       var it = int32View.keys();       for(i=0; i

The join() function of the TypedArray object joins the contents of the typed array as single string and returns it. To this method you can pass a separator to separates the elements of the array.SyntaxIts Syntax is as followstypedArray.join(':')Example Live Demo    JavaScript Array every Method           var int32View = new Int32Array([21, 19, 65, 21, 14, 66, 87, 55 ]);       document.write("");       var contains = int32View.join('');       document.write("."+contains);       document.write("");       document.write(int32View.join(':'));       document.write("");       document.write(int32View.join('-'));       ...

The indexOf() function of the TypedArray object accepts a value and verifies whether the typed array contains the specified element. If so, this function returns the index of the array at which the specified element found, if the element occurred multiple timed this function returns the first index among them. If the array doesn’t contain the specified element the indexOf() function returns -1.SyntaxIts Syntax is as followstypedArray.indexOf(50)Example Live Demo    JavaScript Array every Method           var int32View = new Int32Array([21, 19, 65, 21, 14, 66, 87, 55, 66, 97, 66 ]);       ...

The includes() function of the TypedArray object accepts a value and verifies whether this typed array contains the specified element. If the array contains the given element it returns true else, it returns false.SyntaxIts Syntax is as followstypedArray.includes()Example Live Demo    JavaScript Array every Method           var int32View = new Int32Array([21, 19, 65, 21, 14, 66, 87, 55 ]);       document.write("Contents of the typed array: "+int32View);       document.write("");       var contains = int32View.includes(66);       if(contains) {          document.write("Array contains the specified element");   ...
