More operators: More assignment operators

We’ve seen how to use the assignment operator `=` to assign a value to a variable:

``````const a = 2
let b = 2
var c = 2
``````

This operator has several shortcuts for all the arithmetic operators which let you assign to the first operand the result of the operations with the second operand.

They are:

• `+=`: addition assignment
• `-=`: subtraction assignment
• `*=`: multiplication assignment
• `/=`: division assignment
• `%=`: remainder assignment
• `*=`: exponentiation assignment

Examples:

``````let a = 0
a += 5 //a === 5
a -= 2 //a === 3
a *= 2 //a === 6
a /= 2 //a === 3
a %= 2 //a === 1
``````

To be clear, the above operations are executed one after another, so `a` at the end is 1, not 0
