Javascript | The assignment of values to variables

### Assignment Operators

The equals sign, an assignment operator, will assign a value to a variable. var x = 1; Here we are declaring a variable named x, and assigning the value of 1 to the variable x. x += 4; Here we are adding 4 to the value of x, and reassigning the value for x to the new value which is 5. Next we will discuss many of the different ways to use the operators within Javascript.

• Operator: =
a = b;
means a = b
var x, y = 5;
x = y;
Current x: 5
• Operator: = +=
x += y;
means x = x + y
var x = 5;
x += 5;
Current x: 10
• Operator: = -=
a -= b;
means a = a - b;
var x = 5;
x -= 5;
Current x: 0
• Operator: = *=
x *= y;
means x = x * y
var x = 5;
x *= 5;
Current x: 25
• Operator: = /=
a /= b;
means a = a / b
var x = 5;
x /= 5;
Current x: 1
• Operator: = %=
x %= y;
means x = x % y
var x = 5;
x %= 5;
Current x: 0
• Operator: = <<=
a <<= b;
means a = a << b
• Operator: = >>=
x >>= y;
means x = x >> y
• Operator: = >>>=
a >>>= b;
means a = a >>> b
• Operator: = &=
x <<= y;
means x = x << y
• Operator: ^=
a ^= b;
means a = a ^ b
• Operator: |=
x |= y;
means x = x | y
• Operator: **=
a **= b;
means a = a ** b [Experimental as of 2016; Suggested not to use due to instability]
