All about JavaScript Operators and its types

JavaScript needs no further introduction. Being an important programming language of the programming world, it had been ruling since ages. It is known to be the high-level and interpreted programming language that is used to make interactive web pages. Many times, when websites failed to create the desired engagement or developers want it to be more creative, JavaScript is uses to get the missing things on track. It can be used to enhance the web pages, applications by providing more and interactive user-friendly experience.

Learning JavaScript is also easy. It is easy to learn and quite simple to implement. Thus, learners who want to learn how to use JavaScript can learn it anyhow and anytime.

While learning JavaScript, there’s one term that needs attention of the learners. It’s the JavaScript operators. It is an important part that calls for support from JavaScript. To perform some mathematical or computational calculations, operators are used and JavaScript operators have their own history.

What is a JavaScript Operator?

Generally, an operator is used to manipulate a certain value or operand. An operator is used to perform some kind of mathematical and logical calculations on operands. In short, you can take it as an operator is used to operate the operands.

Operators are used to compare the values and perform arithmetic operations. For example, if you will write 4+5=9, here 4, 5 are the operands while ‘+’ are the operator. In JavaScript, various operators are used to perform different operations. Each and every operator had its own specialty and known for performing a separate type of calculation or operation.

Types of JavaScript operators

There are different types of operators available in JavaScript. Here they are:

Arithmetic Operators: As the name suggests, these types of operators are used to perform the arithmetic operations. Here are few operators that are taken as JavaScript arithmetic operators.

‘+’- it adds two operands

‘-‘- it helps in subtracting the second operand from the first

‘/’- it divides the numerator by the denominator

‘*’- it multiples two operands

%- it generate the output of the integer division

++- It increases an integer value by one

‘—‘- It decreases and integer value by one

Comparison Operators: this JavaScript operator compares the two operands. Here are few comparison operators.

‘==’-It checks whether the two operands are equal or not. Statement will turn true if the operands are equal. ‘===’-It finds the identical ‘!=’-Checks if two operands are equal or not. The condition sets true if the values are not equal. ‘!==’-It implies that the values are unidentical ‘>’-Checks if the value of the left operand is greater than the right one. ‘>=’-Checks if the value of the left operand is greater than or equal to the right one. ‘<’-This Checks if the value of the left operand is less than the value of the right operand ‘<=’-Checks if the value of the left operand is less than or equal to the value of the right operand

Bitwise Operators: these JavaScript bitwise operators are used to perform bitwise operations on operands. The list includes: &: Boolean AND operation on each bit of its integer arguments |: It performs a Boolean OR operation on each bit of its integer arguments ^:This operator performs Bitwise XOR operation ~: It is a unary operator and operates by reversing all the bits in the operand <<: Moves all the bits in its first operand to the left by the number of places specified in the second operand. >>: The left operand’s value is moved right by the number of bits specified by the right operand. Logical Operators: these are the operators that help in performing logical computations. The list includes. &&: Logical AND – If both the operands are non-zero, then the condition becomes true ||: Logical OR – If any of the two operands are non-zero, then the condition is fine. !: Logical NOT – Reverses the logical state of its operand. Assignment Operators: as the name suggests, this JavaScript operators are known for assigning values to the operand. =: Assigns values from the right side operand to the left one +=: It adds the right operand to the left one and generate the output at the left side -=: It subtracts the right operand from the left one and generates the output at the left side. *=: It multiplies the right one with the left operand and assign the answer at the left side /=: It divides the left operand with the right one and assigns the result at the left one. %=: It takes modulus using two operands and display the result at the left one

JavaScript operators are quite helpful in performing all types of mathematical and logical computations. One can use them as and when needed.
