Use the correct assignment operator that will result in x being 15 (same as x = x + y ). Start the Exercise. Well organized and easy to understand Web building tutorials with lots of examples of how to use HTML, CSS, JavaScript, SQL, Python, PHP, Bootstrap, Java, XML and more.
Assignment (=)
The assignment (=) operator is used to assign a value to a variable or property. The assignment expression itself has a value, which is the assigned value. ... JavaScript does not have implicit or undeclared variables. It just conflates the global object with the global scope and allows omitting the global object qualifier during property creation.
JavaScript Assignment Operators
Division Assignment Operator (/=) The Division Assignment operator divides a variable by the value of the right operand and assigns the result to the variable. Example: Javascript. let yoo = 10; const moo = 2; // Expected output 5 console.log(yoo = yoo / moo); // Expected output Infinity console.log(yoo /= 0); Output:
Expressions and operators
This chapter describes JavaScript's expressions and operators, including assignment, comparison, arithmetic, bitwise, logical, string, ternary and more. At a high level, an expression is a valid unit of code that resolves to a value. There are two types of expressions: those that have side effects (such as assigning values) and those that ...
JavaScript Operators
Javascript operators are used to perform different types of mathematical and logical computations. Examples: The Assignment Operator = assigns values. The Addition Operator + adds values. The Multiplication Operator * multiplies values. The Comparison Operator > compares values
JavaScript Assignment Operators
An assignment operator ( =) assigns a value to a variable. The syntax of the assignment operator is as follows: let a = b; Code language: JavaScript (javascript) In this syntax, JavaScript evaluates the expression b first and assigns the result to the variable a. The following example declares the counter variable and initializes its value to zero:
Assignment operators
The basic assignment operator is equal ( = ), which assigns the value of its right operand to its left operand. That is, x = y assigns the value of y to x. The other assignment operators are usually shorthand for standard operations, as shown in the following definitions and examples. Name. Shorthand operator.
Javascript Assignment Operators (with Examples)
Here is the list of all assignment operators in JavaScript: In the following table if variable a is not defined then assume it to be 10. Operator Description Example Equivalent to = Assignment operator: a = 10: a = 10 += Addition assignment operator: a += 10: a = a + 10-= Subtraction assignment operator: a -= 10: a = a - 10 *=
Expressions and operators
Basic keywords and general expressions in JavaScript. These expressions have the highest precedence (higher than operators ). The this keyword refers to a special property of an execution context. Basic null, boolean, number, and string literals. Array initializer/literal syntax. Object initializer/literal syntax.
JavaScript Logical Assignment Operators
The logical OR assignment operator ( ||=) accepts two operands and assigns the right operand to the left operand if the left operand is falsy: In this syntax, the ||= operator only assigns y to x if x is falsy. For example: console .log(title); Code language: JavaScript (javascript) Output: In this example, the title variable is undefined ...

JavaScript Operators (with Examples)
2. JavaScript Assignment Operators. We use assignment operators to assign values to variables. For example, let x = 5; Here, we used the = operator to assign the value 5 to the variable x. Commonly Used Assignment Operators
JavaScript OR (||) variable assignment explanation
The boolean operators in JavaScript can return an operand, and not always a boolean result as in other languages. The Logical OR operator ( ||) returns the value of its second operand, if the first one is falsy, otherwise the value of the first operand is returned. For example: "foo" || "bar"; // returns "foo".
Demystifying JavaScript Operators: What Does That Symbol Mean?
JavaScript operators are symbols that are used to perform operations on operands (values or variables). There are several types of operators in JavaScript, including arithmetic, assignment ...
Addition assignment (+=)
The addition assignment (+=) operator performs addition (which is either numeric addition or string concatenation) on the two operands and assigns the result to the left operand. ... Learn to structure web content with HTML. CSS. Learn to style content using CSS. JavaScript. Learn to run scripts in the browser. Accessibility. Learn to make the ...
Bitwise AND Assignment (&=) Operator in JavaScript
The Bitwise AND Assignment Operator is represented by "&=". This operator uses the binary representation of both operands and performs the bitwise AND operation and then assigns the result to the left operand. This can also be explained as applying the logical AND operation to the first operand and second operand and after that assigning ...

The other assignment operators are usually shorthand for standard operations, as shown in the following definitions and examples. Name. Shorthand operator.
Bitwise OR Assignment (|=) Operator in JavaScript
This operator is used to perform a bitwise OR operation on both operands and assign the result to the left operands. Syntax: a |= b. Where -. a = First operand. b = Second operand. Example 1: In this example, we will use basic numeric values to perform Bitwise OR Assignment Operation. Javascript.
Logical OR assignment (||=)
Description. Logical OR assignment short-circuits, meaning that x ||= y is equivalent to x || (x = y), except that the expression x is only evaluated once. No assignment is performed if the left-hand side is not falsy, due to short-circuiting of the logical OR operator. For example, the following does not throw an error, despite x being const: js.
Operator precedence
This is because the assignment operator returns the value that is assigned. First, b is set to 5. Then the a is also set to 5 — the return value of b = 5, a.k.a. right operand of the assignment. As another example, the unique exponentiation operator has right-associativity, whereas other arithmetic operators have left-associativity.
Addition Assignment (+=) Operator in Javascript
JavaScript Addition assignment operator (+=) adds a value to a variable, The Addition Assignment (+ =) Sums up left and right operand values and then assigns the result to the left operand. The two major operations that can be performed using this operator are the addition of numbers and the concatenation of strings. Syntax: a += b.
Python Operators
Assignment Operators in Python. Let's see an example of Assignment Operators in Python. Example: The code starts with 'a' and 'b' both having the value 10. It then performs a series of operations: addition, subtraction, multiplication, and a left shift operation on 'b'.
Right Shift Assignment(>>=) Operator in JavaScript
The Right Shift Assignment Operator is represented by ">>=". This operator shifts the first operand to the right and assigns the result to the variable. It can also be explained as shifting the first operand to the right in a specified amount of bits which is the second operand integer and then assigning the result to the first operand. Syntax:
Left shift (<<)
The << operator is overloaded for two types of operands: number and BigInt.For numbers, the operator returns a 32-bit integer. For BigInts, the operator returns a BigInt. It first coerces both operands to numeric values and tests the types of them. It performs BigInt left shift if both operands become BigInts; otherwise, it converts both operands to 32-bit integers and performs number left shift.
