JavaScript Operators: The Basics You Need to Know

WHAT ARE OPERATORS?

in javascript , operators are basically symbol that performs operation on variable or values by using operands.

for example;

here we can see result is a variable in which we are storing operands(5,3) with operator(+).

yeah i do like it man

1.ARITHMETIC OPERATORS:-

Arithmetic operators in JavaScript are just like the math moves you already know.
They help us perform basic calculations like adding numbers, subtracting, multiplying, dividing, and finding the remainder.”

for more extreme cases people have doubt what % do it actually provide u remainder.

2.COMPARISION OPERATOR

these are the operator which compares the value and return boolean functionality like true or false .

Operator	Meaning
==	Equal value
===	Equal value and data type
!=	Not equal
>	Greater than
<	Less than

in this example we can clearly se comparing only value and

=== comparing datatype,value

3.LOGICAL OPERATOR:-

Logical operators are used to combine or modify conditions in JavaScript. They help the program make decisions by checking whether multiple conditions are true or false.

Think of them as decision makers that help your code answer questions like:

• Should both conditions be true?

• Is at least one condition true?

• Should the result be the opposite?

so the ouput will be true ,true ,false

• age > 18 && hasID → true
  Both conditions are true.

• age < 18 || hasID → true
  One condition (hasID) is true.

• !hasID → false
  The NOT operator reverses the value of true

4.ASSIGNMENT OPERATOR:-

Assignment operators are used to assign values to variables in JavaScript.
They help store data in a variable and also allow us to update or modify the value easily*.*

lets for example

let x=10;

if we console log this one u can easily be found output will be 10

let x+=10

here we used += a it simply sayes ki x=x+10;

if we console out that particular thing answer would be 20.

Operator	Meaning	Example
=	Assign value	x = 5
+=	Add and assign	x += 3//result=x+3
-=	Subtract and assign	x -= 2//result=x-3
*=	Multiply and assign	x *= 2//result=x*2
/=	Divide and assign	x /= 2//result=x/2

here output will be 15;

here output will be 7.

here output will be 20 x*2;

here output will be 5 because x/2.
