What is an operator in JavaScript- An operator in JavaScript is a special symbol that performs a specific action on one or more values we can call it an operand. Operators in JavaScript that help you perform calculations, compare values, assign values to variables, and make decisions in your code. In today’s article, we will learn more about what are the 4 types of operators in JavaScript.
Types of Operators in JavaScript
- Arithmetic operator: Arithmetic operators are used to perform math operations.
Example: Addition (+), Subtraction(-), Multiplication(*), Division(/).
- Assignment operator: The assignment operator is used to assign values to variables.
Example: Assign value ( = ), add an assign (+=).
- Comparison operator: A comparison operator is used to compare two values.
Example: ( ==) equal to, (!=) not equal to,(>) greater than.
- Logical operator: Logical operator is used to combine multiple conditions.
Example: (&&)and, (||) OR, (!) not.
- String operators: String operators are used to manipulate strings.
Example: (+) can also concatenate string.
Operator in JavaScript with an Example
In JavaScript, an assignment operator is used to assign value to a variable. We all know the most common assignment operator is the equal sign (=) but others combine assignment with arithmetic operations the syntax of the assignment operator is, let’s see the basic assignment operator with their example.
Let a = b;
Basic assignment operator
- (=): This operator assigns the value on its right to the variable on its left.
Compound assignment operator
These are the combined combinations often operations with assignments Let’s see a few examples.
- Addition assignment (+=): In this addition assignment add the right operant to the left operant and assign the result to the left operant.
- Subtraction assignment (-=): In the subtraction assignment abstract the right operant from the left opened and assign the result.
- Multiplication assignment(*=): Multiplication assignment multiply left operand by the right and assign the result.
- Division assignment (/=): The division assignment divides the left operant from the right operant and assigns the result.
