• JavaScript’s assignment operators are used to assign variables to different values.
• Assignment operators each have a symbol known as the operator that is used to perform the operation.
• Equals: used to assign a variable to a value
  • Operator: =
    

let example = 5;
let name = "Alex";
name = example;

Q : What is the value of the variable named “name”?

• Plus-Equals: assigning a variable to its original value plus some specified value
  • Operator: +=
  • shorthand for x = x + number

x = 5;
y = 30;
x += 10;
x += y;
y += x;

Q : What is the value of variable y?

• Minus-Equals : assigning a variable to its original value minus some specified value
  • Operator: -=
  • shorthand for x = x - number

x = 50;
y = 23;
x -= 12;
x -= y;
y -= x;

Q : What is the value of variable y?

• Times-Equals : assigning a variable to its original value times some specified value
  • Operator: *=
  • shorthand for x = x * number

x = 13;
y = 9;
x *= 3;
x *= y;
y *= x;

Q : What is the value of variable y?

• Divide-Equals : assigning a variable to its original value divided by some specified value
  • Operator: /=
  • x = x / number
  • less common

x = 348;
y = 24;
x /= 58;
y /= x;

Q : What is the value of variable y?

• Modulus-Equals : assigning a variable to its original value modulus some specified value
  • Operator: %=
  • also rarely used

x = 49;
y = 17;
x %= 12;
y %= x;
