Zero Fill Right Shift (>>>) Bitwise Operator in JavaScript Last Updated : 23 Jul, 2025 Comments Improve Suggest changes Like Article Like Report JavaScript Zero Fill Right Shift Operator or Unsigned Right Shift Operator(>>>) is used for operating on the two operands. The first operand is the number and the right operand specifies the bits to shift towards the right modulo 32. In this way, the excess bits which are shifted towards the right are discarded and zero bits are added towards the left, as a result, the sign bit is now zero and the number becomes positive always. Let's look at the table below to better understand the output of the Zero Fill Right Shift Operation. A6 ( 00000000000000000000000000000110 )B1 ( 00000000000000000000000000000001 )OUTPUT ( A >>> B )3 ( 00000000000000000000000000000011 ) Syntax: a>>>b Example 1: In this example, we will use the unsigned right shift operator on the numbers. JavaScript let a = 4; let b = -1 console.log(a>>>1); console.log(b>>>4); Output: The output will never be negative for any number 2 268435455 Example 2: In this example, we will use the unsigned right shift operator on Data Types that are not Number. JavaScript let a = "HEllo"; let b =true; let c = null; console.log(a>>>1); console.log(b>>>1); console.log(c>>>1); Output: The output of the unsigned right shift operator on non numbers will be zero. 0 0 0Supported Browsers: ChromeEdgeFirefoxOperaSafariWe have a complete list of JavaScript Bitwise Operators, to check those please go through, the JavaScript Bitwise Operators article Comment More info S shobhit_sharma Follow Improve Article Tags : JavaScript Web Technologies Explore JavaScript BasicsIntroduction to JavaScript4 min readVariables and Datatypes in JavaScript6 min readJavaScript Operators5 min readControl Statements in JavaScript4 min readArray & StringJavaScript Arrays7 min readJavaScript Array Methods7 min readJavaScript Strings6 min readJavaScript String Methods9 min readFunction & ObjectFunctions in JavaScript5 min readJavaScript Function Expression3 min readFunction Overloading in JavaScript4 min readObjects in Javascript4 min readJavaScript Object Constructors4 min readOOPObject Oriented Programming in JavaScript3 min readClasses and Objects in JavaScript4 min readWhat Are Access Modifiers In JavaScript ?5 min readJavaScript Constructor Method7 min readAsynchronous JavaScriptAsynchronous JavaScript2 min readJavaScript Callbacks4 min readJavaScript Promise4 min readEvent Loop in JavaScript4 min readAsync and Await in JavaScript2 min readException HandlingJavascript Error and Exceptional Handling6 min readJavaScript Errors Throw and Try to Catch2 min readHow to create custom errors in JavaScript ?2 min readJavaScript TypeError - Invalid Array.prototype.sort argument1 min readDOMHTML DOM (Document Object Model)9 min readHow to select DOM Elements in JavaScript ?3 min readJavaScript Custom Events4 min readJavaScript addEventListener() with Examples9 min readAdvanced TopicsClosure in JavaScript4 min readJavaScript Hoisting6 min readJavascript Scope3 min readJavaScript Higher Order Functions7 min readDebugging in JavaScript4 min read Like
