JavaScript Operators

JavaScript operators are special symbols or keywords used to perform operations on values and variables. These operations include mathematical calculations, comparisons, logical evaluations, value assignments, and more. Understanding operators is essential for writing functional and efficient code.

1. Arithmetic Operators

Arithmetic operators perform basic mathematical operations:

---

2. Assignment Operators

Assignment operators are used to assign or update values in variables:

---

3. Comparison Operators

These operators compare values and return true or false:

---

4. Logical Operators

Logical operators combine multiple conditions:

---

5. String Operator

The + operator can also concatenate strings:

---

6. Ternary Operator

A shorthand for if-else conditions:

---

7. Type Operators

Used to check types or instances:

---

8. Bitwise Operators

Operate on binary values:

Key Takeaways

• Operators let you manipulate values, compare data, assign results, and control logic flow.
• Arithmetic operators perform math; logical operators handle conditions.
• Use strict equality (===) for safer comparisons.
• Ternary operator is great for concise conditionals.
• Type and bitwise operators offer advanced control when needed.
