  javascript : Object  .isString Target: Applicable with any javascript  Object  Variable  that holds string value . Description : When an object holds an string value then it return  true   otherwise  undefined   . basically it is defined in String prototype. Many time in programming we face a problem that an object variable holds String value or other object structure then it help us. Before writing the code of String manipulation we can check whether a variable holds String value or not. Note: It is an property of String, that is defined in String Prototype. It is useful to check an object variable is String or any other type. another way to check variable holds string value is "typeof(variable) == 'string'" Syntax: ObjectVariable  .isString return  true  when object hold's String value otherwise  undefined Usase: var obj = 'abcd'; console.log('typeof obj = ' + typeof(obj)); if(obj.isString){      co...

  javascript : Object .isNodeList Target: Applicable with any javascript  Object  Variable  that holds DOM Elements List. Description : When an object holds an html domElementsList/NodeList/htmlCollection then it return  true  otherwise  undefined . basically it is defined in NodeList/htmlCollection prototype. Many time in programming we face a problem that an object variable holds DomElementList or other object structure then it help us. Before writing the code of DomElementList manipulation we can check whether a variable holds domElementsList/NodeList/htmlCollection or not. Note: It is an property of DomElementsList that is defined in NodeList/htmlCollection Prototype. It is useful to check an object variable is DomElementsList or any other type. When we check the typeof(object_variable) it return 'object' not 'NodeList/htmlCollection'. Syntax: Object .isNodeList return  true  when object hold's NodeList/htmlCollection otherwise  unde...

  javascript : Object .isDomElement Target: Applicable with any javascript  Object  Variable  that holds DOM Element . Description : When an object holds an html domElement then it return  true  otherwise  undefined . basically it is defined in DomElement prototype. Many time in programming we face a problem that an object variable holds DomElement or other object structure then it help us. Before writing the code of DomElement manipulation we can check whether a variable holds DomElement or not. Note: It is an property of DomElement that is defined in DomElement Prototype. It is useful to check an object variable is DomElement or any other type. When we check the typeof(object_variable) it return 'object' not 'DomElement/Node'. Syntax: Object .isDomElement return  true  when object hold's DomElement otherwise  undefined Usase: var obj = document.querySelector('div') if(obj.isDomElement){      console.log('Object hold...

  javascript : Object .isNumber Target: Applicable with any javascript  Object/String  Variable  that holds numeric value . Description : When an object holds an numeric value then it return  true  otherwise  undefined . basically it is defined in Number prototype. Many time in programming we face a problem that an object variable holds Numeric value or other object structure then it help us. Before writing the code of Numeric calculation we can check whether a variable holds Numeric value or not. Note: It is an property of Numeric, that is defined in Numeric Prototype. It is useful to check an object variable is Numeric or any other type. another way to check variable holds numeric value is "typeof(variable) = 'number'" but when variable holds string numeric value it return "typeof(variable) = 'string'" Syntax: Object .isNumber return  true  when object hold's Numeric value otherwise  undefined Usase: var obj = 55; console.log('typeof o...

  javascript : Object .isDate Target: Applicable with any javascript  Object  Variable  that holds date value . Description : When an object holds an date then it return  true  otherwise  undefined . basically it is defined in Date prototype. Many time in programming we face a problem that an object variable holds Date value or other object structure then it help us. Before writing the code of Date manipulation we can check whether a variable holds Date value or not. Note: It is an property of Date, that is defined in Date Prototype. It is useful to check an object variable is Date or any other type. When we check the typeof(object_variable) it return 'object' not 'date'. Syntax: Object .isDate return  true  when object hold's Date value otherwise  undefined Usase: var obj = 'date'; if(obj.isDate){      console.log('Object holds date value'); } else{      console.log('Object is not a date value'); ...
