JS Assignment
In JavaScript, assignment operators are used to assign values to variables. They are a shorthand way of writing a statement that would otherwise be written as two separate statements: one to declare the variable and another to assign a value to it. The basic assignment operators are:
- Assignment (=): Assigns a value to a variable.
Example:
let x;
x = 5; // Assigns the value 5 tothe variable x
console.log(x);// Output: 5
- Addition assignment (+=): Adds a value to a variable and assigns the result to the variable.
Example:
let x = 5;
x += 3; // Adds 3 to x andassigns the result to x
console.log(x); // Output: 8
- Subtraction assignment (-=): Subtracts a value from a variable and assigns the result to the variable.
Example:
let x = 5;
x -= 3; // Subtracts 3 from xand assigns the result to x
console.log(x); // Output: 2
- Multiplication assignment (*=): Multiplies a variable by a value and assigns the result to the variable.
Example:
let x = 5;
x *= 3; // Multiplies x by 3 andassigns the result to x
console.log(x); // Output: 15
- Division assignment (/=): Divides a variable by a value and assigns the result to the variable.
Example:
let x = 5;
x /= 3; // Divides x by 3 andassigns the result to x
console.log(x); // Output:1.6666666666666667
- Modulo assignment (%=): Divides a variable by a value and assigns the remainder to the variable.
Example:
let x = 5;
x %= 3; // Divides x by 3 andassigns the remainder to x
console.log(x); // Output: 2
These assignment operators can be used to simplify your code and make it more readable by combining the declaration and assignment of variables into a single statement.
