The byteOffset property of the TypedArray represents the offset of the current object.SyntaxIts Syntax is as followstypedArray.byteOffset();Example Live Demo    JavaScript Example           var buffer = new ArrayBuffer(156);       var float32 = new Float32Array(buffer);       document.write(float32.byteOffset);     Output0

The byteLength property of the TypedArray object represents the length of its(in bytes)TypedArray.SyntaxIts Syntax is as followstypedArray.byteLength();Example Live Demo    JavaScript Example           var buffer = new ArrayBuffer(156);       var float32 = new Float32Array(buffer);       document.write(float32.byteLength);     Output156

The buffer property of the TypedArray represents the ArrayBuffer of the current TypedArray.SyntaxIts Syntax is as followsobj.buffer;Example Live Demo    JavaScript Example           var buffer = new ArrayBuffer(156);       var float32 = new Float32Array(buffer);       document.write(float32.buffer.byteLength);     Output156

The name property of the TypedArray object represents the name of the typed array in string (format)i.e. one of Int8Array, Uint8Array, Uint8ClampedArray, Int16Array, Uint16Array, Int32Array, Uint32Array, Float32Array, Float64Array.SyntaxIts Syntax is as followsFloat32Array.name;Example Live Demo    JavaScript Example           var nameOfarray1 = Float32Array.name;       document.write("name of array1: "+nameOfarray1);       document.write("");       var nameOfarray2 = Int16Array.name;       document.write("name of array2: "+nameOfarray2);     Outputname of array1: Float32Array name of array2: Int16Array

The BYTES_PER_ELEMENT property of the Typed Array represents the number of bytes in each element in it.SyntaxIts Syntax is as followsFloat32Array.BYTES_PER_ELEMENT;Example Live Demo    JavaScript Example           var sizeOfFloat64Array = Float32Array.BYTES_PER_ELEMENT;       document.write("Size of the float 32 array: "+sizeOfFloat64Array);       document.write("");       var sizeOfInt16Array = Int16Array.BYTES_PER_ELEMENT;       document.write("Size of the int 16 array: "+sizeOfInt16Array);     OutputSize of the float 32 array: 4 Size of the int 16 array: 2

The decodeURIComponent() function accepts a string value representing an encoded URI (Uniform Resource Identifier) decodes it and returns the result.SyntaxIts Syntax is as followsencodeURIComponent('http://www.qries.com/');Example Live Demo    JavaScript Example           var encodedData = encodeURIComponent('http://www.qries.com/?x=шеллы');       document.write("Encoded Data: "+encodedData);       document.write("");       var decodedData = decodeURIComponent(encodedData);       document.write("Decoded Data: "+decodedData);     OutputEncoded Data: http%3A%2F%2Fwww.qries.com%2F%3Fx%3D%D1%88%D0%B5%D0%BB%D0%BB%D1%8B Decoded Data: http://www.qries.com/?x=шеллы

The isFinite() function accepts a value and determines whether the given value is a finite number or not. If so, this method returns true else it returns false. You can also invoke this method using Number object.SyntaxIts Syntax is as followsisFinite(5655);Example Live Demo    JavaScript Example           var result1 = Math.min();       document.write(isFinite(result1));       document.write("");       var result2 = Number.isFinite(100/0);       document.write(result2);       document.write("");       var result3 = Math.max(25, 36, 862);       document.write(isFinite(result3));     Outputfalse false true

The parseFloat() function accepts two parameters one is a string representing a number and another is a number representing the radix and returns an integer of the given radix.SyntaxIts Syntax is as followsnum.parseFloat('4524', 8);Example Live Demo    JavaScript Example           var result1 = parseFloat(Math.PI);       document.write("Result: "+result1);       document.write('');       var result2 = parseFloat("245.12@welcome");       document.write("Result: "+result2);       document.write('');       var result3 = parseFloat("11111100.010");       document.write("Result: "+result3);     OutputResult: 3.141592653589793 Result: 245.12 Result: 11111100.01

The byteLength property of the SharedArrayBuffer returns an unsigned, 32-bit integer that specifies the size/length of a SharedArrayBuffer. Syntax Its Syntax is as follows sharedArrayBuffer.byteLength Example Live Demo JavaScript Example var sharedArrayBuffer = new SharedArrayBuffer(8); var result = sharedArrayBuffer.byteLength; document.write("length of the shared array buffer is: " + result); Output length of the shared array buffer is: 8
