The W3Schools online code editor allows you to edit code and view the result in your browser Dive into the world of JavaScript operators, from arithmetic and comparison to logical and assignment operators. JavaScript operators are used to assign and compare values, arithmetic operations, and more. JavaScript (JS) is a lightweight interpreted (or just-in-time compiled) programming language with first-class functions. Primitive Data Types In JavaScript, a primitive value is a single value with no properties or methods. Operators with higher precedence become the operands of operators with lower precedence. They are the building blocks of Learn about different types of JavaScript operators, such as arithmetic, assignment, comparison, logical, bitwise, string and miscellaneous operators. Assignment Operators 3. JavaScript Operators JavaScript assignment operators (=) assign values to variables: JavaScript String Operators The + operator can also be used to add (concatenate) strings.

There are different types of JavaScript operators: 1. The Math object is static. A JavaScript variable can hold 8 types of data. All methods and properties can be used without creating a Math object first. JavaScript Promises A JavaScript Promise is an object representing the completion or failure of an asynchronous operation and its values. JavaScript has 7 primitive data types: string number boolean bigint symbol null undefined The typeof For more details on language-specific operators, check out Python Operators, JavaScript Operators, Java Operators, and C++ Operators. This chapter documents all the JavaScript language operators, expressions and keywords. Given that x = 5, the table below explains the comparison In JavaScript, an operator is a symbol that performs an operation on one or more operands, such as variables or values, and returns a result.
