QUESTION 1

List the symbols for each of the below Javascript operators

1. Arithmetic Operators

• Addition +

• Subtraction -

• Multiplication / Division

2. Assignment Operators = assignment += add and assignment -= subtract and assignment *= multiply and assignment

3. Comparison Operators

greater than < less than = greater than equals to <= less than equals to === strict equality !== strictly inequality

4. Logical Operators && And || or ! logical not

5. Bitwise Operators | OR Sets each bit to 1 if one of two bits is 1 ^ XOR Sets each bit to 1 if only one of two bits is 1 ~ NOT Inverts all the bits << Zero fill left shift

---

QUESTION 2 For each JavaScript Operator, write 2 examples.

Arithemtic operation

// example

1. function multiply (number1, number2) { return number1 * number2; } console.log(multiply(20, 5)) // Answer: 100

example console.log(100/3) // Answer: 33.3

---

2. Assignment operators

// example let myName = 'mykel'; console.log(myName) // Answer: mykel

let x = 10; x += 5; console.log(x) // Answer: 15

---

3. Comparison operators

// example let track = 'backend'; let program = 'frontend'; console.log(track == program) // Answer: false

console.log(5 >= 4) // Answer: true

---

4. Logical Operators

example console.log(14 > 7 && 5 <= 5) // Answer: true

example const a = 3; const b = -2; console.log(!(a > 0 || b > 0)); // Answer: false

---

5. Bitwise Operators // example let x = 5 | 1; console.log(x) // Answer: 5

example let x = -100; x <<= 5; console.log(x) // Answer: -3200

Question 4

What is the result when the following program is executed? for (let i = 1; i < 20; i += 7) { console.log(i) }

Answer: 1 8 15
