operator

Sure, here's a more comprehensive list including all the symbols for each type of operator in JavaScript and one example for each:

1. Arithmetic Operators

Symbols: +, -, *, /, %, ++, --, **
Examples:

let add = 5 + 3;      // 8
let sub = 5 - 3;      // 2
let mul = 5 * 3;      // 15
let div = 5 / 3;      // 1.6666...
let mod = 5 % 3;      // 2
let num = 5; 
num++;                // 6
num--;                // 5 again
let exp = 5 ** 3;     // 125

2. Assignment Operators

Symbols: =, +=, -=, *=, /=, %=, **=
Examples:

let x = 5;     // 5
x += 3;        // 8
x -= 3;        // 5
x *= 3;        // 15
x /= 3;        // 5
x %= 3;        // 2
x **= 3;       // 8

3. String Operators

Symbol: + (there's only one symbol for string operation which is used for concatenation)
Example:

let text = "Hello" + " " + "World"; // "Hello World"

4. Comparison Operators

Symbols: ==, ===, !=, !==, >, <, >=, <=
Examples:

let isEqual = (5 == '5');         // true
let isStrictEqual = (5 === '5');  // false
let isNotEqual = (5 != '5');      // false
let isStrictNotEqual = (5 !== '5'); // true
let isGreater = (5 > 3);          // true
let isLesser = (5 < 3);           // false
let isGreaterOrEqual = (5 >= 5);  // true
let isLesserOrEqual = (5 <= 5);   // true

5. Logical Operators

Symbols: &&, ||, !
Examples:

let and = (true && false);   // false
let or = (true || false);    // true
let not = !(true);           // false

6. Bitwise Operators

Symbols: &, |, ^, ~, <<, >>, >>>
Examples:

let bitwiseAND = (5 & 3);          // 1
let bitwiseOR = (5 | 3);           // 7
let bitwiseXOR = (5 ^ 3);          // 6
let bitwiseNOT = (~5);             // -6
let bitwiseLeftShift = (5 << 1);   // 10
let bitwiseRightShift = (5 >> 1);  // 2
let bitwiseZeroFillRightShift = (5 >>> 1);  // 2

7. Conditional (Ternary) Operator

Symbol: ? :
Example:

let status = (age >= 18) ? "adult" : "minor"; // "adult" if age is 18 or over, otherwise "minor"

8. Nullish Coalescing Operator

Symbol: ??
Example:

let username = userInput ?? "defaultUser"; // "defaultUser" if userInput is null or undefined

This set of examples should give you a comprehensive view of the various operators available in JavaScript, represented by their respective symbols, along with practical usage examples.
