→ Logical operator?

→ String operator?

Let me explain!🧵👇

📌 Arithmetic operator?

→ It is used to perform mathematical calculations.

👀 +, -, %, *, **, etc

→ ** is a square operator or power operator.

👀 2**3 = 2x2x2

→ % is a modulus operator, not a percentage.

→ It is used to find the remainder of an expression.

👀 11 % 10 = remainder ( 1 )

📌 Prefix & Postfix operator?

→ One special operator is an increment or decrement operator in any programming language.

→ There are 2 types of increment or decrement operators.

1️⃣ Prefix
2️⃣ Postfix

📌 Pre means Before (like prepaid)
📌 Post means After (like postpaid)

1️⃣ Prefix: Prefix increment or decrement the value and returns a "new" value.

2️⃣ Postfix: Postfix increment or decrement the value and returns an "old" value.

⛔ This operator only applied to variables, not on values!!!

📌 Assignment operator?

→ It is used to assign value to a variable.

👀 =, +=, -=, *=, **=, etc.

→ "+=" This operator activates at the same time.

👀 c *= 10??👇

📌 Comparision operator?

→ This operator compares 2 values and returns a boolean value.

→ true and false are boolean values.

📌 == VS === operator?

→ In javascript, there are 2 types of equality operators.

1️⃣ Loose equality operator ( == )

→ When we compare between 2 values then the "data types" of that variables are not considered.

⛔In short: only data is compared with loose equality operators.

2️⃣ Strict equality operator ( === )

→ When we compare between 2 values then the "data types" of that variables are also considered.

⛔ In short: data and data types both are compared with strict equality operators.

📌 Logical operator?

→ It's used to perform logical operations & return a boolean value.

→ && (AND) : true when both values are true.
→ || (OR): true when both or only one value are true.
→ ! (NOT): if true then false or vice-versa.

⛔ More about in the upcoming thread!

📌 String operator?

→ You can use the + operator to add 2 or more strings.

→ Its also known as concatenation.

→ Or you can also use the addition assignment( +=) operator for adding the strings.
