Are String Objects in JavaScript? Last Updated : 15 Apr, 2025 Comments Improve Suggest changes Like Article Like Report Strings in JavaScript are one of the primitive data types, alongside numbers, booleans, null, undefined, bigint, and symbols. Unlike objects, primitives do not have methods or properties of their own. However, when you attempt to call a method or access a property on a string, JavaScript automatically wraps the string in a String object to provide access to methods. JavaScript let s = "hello"; console.log(typeof s); console.log(s.length); // Example with a number let x = 42; console.log(x.toString()); // Example with a boolean let y = true; console.log(y.toString()); /* Internal Working of primitives to be treeated as objects // Temporary wrapper object let temp = new String("hello"); console.log(temp.length); // 5 // The wrapper is discarded after use temp = null; */ Outputstring 5 42 true The String ObjectJavaScript has a built-in String object that can be explicitly used to create string objects. This is different from primitive strings. JavaScript const s = new String("Hello"); console.log(typeof s); Outputobject Key Differences Between Primitives and String ObjectsFeaturePrimitive StringString ObjectType"string""object"Memory EfficiencyMore efficientLess efficientUse CaseHighly used in creating stringRarely usedTip: Always prefer primitive strings for simplicity and performance.Why the Confusion?The confusion arises because strings appear to have methods and properties like objects, but they are primitives. The temporary wrapping of primitives into String objects is what enables this behavior. JavaScript const s = "Test"; console.log(s.constructor === String); Outputtrue Here, JavaScript implicitly wraps the string in a String object to access the .constructor property.

It stores data as key-value pairs, where each key is a unique identifier for the associated value. Objects are dynamic, which means the properties can be added, modified, or deleted at runtime.There are two primary w 4 min read Creating objects in JavaScript An object in JavaScript is a collection of key-value pairs, where keys are strings (properties) and values can be any data type. Objects can be created using object literals, constructors, or classes.

Yes, JavaScript arrays are actually specialized objects, with indexed keys and special properties.
