JavaScript, operators and expressions are fundamental concepts that play a crucial role in building and manipulating values and data. Here’s an overview of operators and expressions in JavaScript: Operators<\/strong>: 1. Arithmetic Operators<\/strong>: Addition (+)<\/strong>: Adds two values together.<\/p>\n Subtraction (-):\u00a0<\/strong> Subtracts the second value from the first.<\/p>\n Multiplication (*):<\/strong> Multiplies two values.<\/p>\n Division (\/):\u00a0<\/strong>Divides the first value by the second.<\/p>\n Modulus (%):<\/strong> Returns the remainder of the division operation.<\/p>\n Increment (++):<\/strong> Increases the value of a variable by 1.<\/p>\n Decrement (–):<\/strong> Decreases the value of a variable by 1.<\/p>\n Exponentiation () [ES6]**:<\/strong> Raises the first value to the power of the second.<\/p>\n Arithmetic operators follow the order of operations (PEMDAS\/BODMAS), meaning operations inside parentheses are performed first, followed by exponentiation, multiplication, division, addition, and subtraction.<\/p>\n Assignment operators in JavaScript are used to assign values to variables. They allow you to modify the value of a variable by assigning a new value or by performing an operation on the existing value. Here’s a list of assignment operators in JavaScript along with examples:<\/p>\n Assignment (=): <\/strong>Assigns a value to a variable.<\/p>\n Addition Assignment (+=): <\/strong>Adds a value to the variable’s current value and assigns the result back to the variable.<\/p>\n Subtraction Assignment (-=): <\/strong>Subtracts a value from the variable’s current value and assigns the result back to the variable.<\/p>\n Multiplication Assignment (*=): <\/strong>Multiplies the variable’s current value by a value and assigns the result back to the variable.<\/p>\n Division Assignment (\/=): <\/strong>Divides the variable’s current value by a value and assigns the result back to the variable.<\/p>\n Modulus Assignment (%=): <\/strong>Calculates the remainder of dividing the variable’s current value by a value and assigns the result back to the variable.<\/p>\n Assignment operators are often used to update the value of a variable based on a calculation or modification. They can also be combined with other operators to perform more complex operations.<\/p>\n Keep in mind that assignment operators work from right to left. The operation on the right side is performed first, and then the result is assigned to the variable on the left side.<\/p>\n Also read, Javascript Data Types<\/a><\/span><\/p>\n 3. Comparison Operators: Equal To (==<\/strong>): Checks if two values are equal, regardless of their data types (type coercion is applied).<\/p>\n Not Equal To (!=): <\/strong>Checks if two values are not equal, regardless of their data types.<\/p>\n Strict Equal To (===): <\/strong>Checks if two values are equal and have the same data type (no type coercion is applied).<\/p>\n Strict Not Equal To (!==): <\/strong>Checks if two values are not equal or have different data types.<\/p>\n Greater Than (>): <\/strong>Checks if the value on the left is greater than the value on the right.<\/p>\n Less Than (<): <\/strong>Checks if the value on the left is less than the value on the right.<\/p>\n Checks if the value on the left is greater than or equal to the value on the right.<\/p>\n Less Than or Equal To (<=): <\/strong>Checks if the value on the left is less than or equal to the value on the right.<\/p>\n Comparison operators are commonly used in conditional statements and loops to make decisions based on the comparison results. They allow you to evaluate and control the flow of your JavaScript code based on specific conditions.<\/p>\n Note:<\/strong> Note: In the upcoming chapter<\/strong>, we will delve into the details of pending operators and provide a comprehensive description.<\/span><\/p>\n Note:<\/strong>\u00a0We welcome your feedback at\u00a0<\/span>Easy coding School<\/a>.

\nOperators are symbols that perform operations on values or variables. JavaScript provides a variety of operators for performing different types of operations.<\/p>\n
\nArithmetic operators in JavaScript are symbols used to perform mathematical calculations on numeric values (operands). They allow you to perform basic arithmetic operations such as addition, subtraction, multiplication, division, and more. Here’s a list of arithmetic operators in JavaScript along with examples:<\/p>\nlet sum = 5 + 3; \/\/ sum is 8<\/code><\/pre>\n<\/div>\nlet difference = 10 - 5; \/\/ difference is 5<\/code><\/pre>\n<\/div>\nlet product = 2 * 6; \/\/ product is 12<\/code><\/pre>\n<\/div>\nlet<\/span> quotient = <\/span>10<\/span> \/ <\/span>2<\/span>; <\/span>\/\/ quotient is 5<\/span><\/code><\/pre>\n<\/div>\nlet remainder = 7 % 3; \/\/ remainder is 1<\/code><\/pre>\n<\/div>\nlet count = 5;\r\ncount++; \/\/ count is now 6<\/code><\/pre>\n<\/div>\nlet quantity = 8;\r\nquantity--; \/\/ quantity is now 7<\/code><\/pre>\n<\/div>\nlet result = 2 ** 3; \/\/ result is 8 (2 raised to the power of 3)<\/code><\/pre>\n<\/div>\nlet result = 2 + 3 * 4; \/\/ result is 14, not 20 (3 * 4 is calculated first)<\/code><\/pre>\n<\/div>\nlet x = 10; \/\/ x is assigned the value 10<\/code><\/pre>\n<\/div>\nlet y = 5;\r\ny += 3; \/\/ y is now 8 (5 + 3)<\/code><\/pre>\n<\/div>\nlet z = 7;\r\nz -= 2; \/\/ z is now 5 (7 - 2)<\/code><\/pre>\n<\/div>\nlet a = 3;\r\na *= 4; \/\/ a is now 12 (3 * 4)<\/code><\/pre>\n<\/div>\nlet b = 20;\r\nb \/= 5; \/\/ b is now 4 (20 \/ 5)<\/code><\/pre>\n<\/div>\nlet c = 15;\r\nc %= 7; \/\/ c is now 1 (15 % 7)<\/code><\/pre>\n<\/div>\nlet total = 0;\r\ntotal += 5; \/\/ total is now 5\r\ntotal *= 2; \/\/ total is now 10<\/code><\/strong><\/pre>\n<\/div>\n
\n<\/strong>Comparison operators in JavaScript are used to compare two values and determine the relationship between them. These operators return a Boolean value (true or false) based on whether the comparison is true or false. Here’s a list of comparison operators in JavaScript along with examples:<\/p>\nlet x = 5;\r\nlet y = '5';\r\nconsole.log(x == y); \/\/ true (5 is equal to '5' after type coercion)<\/code><\/pre>\n<\/div>\nlet a = 10;\r\nlet b = '15';\r\nconsole.log(a != b); \/\/ true (10 is not equal to '15' after type coercion)<\/code><\/pre>\n<\/div>\nlet p = 7;\r\nlet q = '7';\r\nconsole.log(p === q); \/\/ false (7 and '7' have different types)<\/code><\/pre>\n<\/div>\nlet m = true;\r\nlet n = 1;\r\nconsole.log(m !== n); \/\/ true (true and 1 have different types)<\/code><\/pre>\n<\/div>\nlet age = 18;\r\nconsole.log(age > 16); \/\/ true (18 is greater than 16)<\/code><\/pre>\n<\/div>\nlet score = 85;\r\nconsole.log(score < 90); \/\/ true (85 is less than 90) Greater Than or Equal To (>=):<\/code><\/pre>\n<\/div>\nlet price = 25;\r\nconsole.log(price >= 20); \/\/ true (25 is greater than or equal to 20)<\/code><\/pre>\n<\/div>\nlet quantity = 5;\r\nconsole.log(quantity <= 5); \/\/ true (5 is less than or equal to 5)<\/code><\/pre>\n<\/div>\n
