Assignment

Simple assignment

The = operator assigns a value to a variable, property, or index:

count = 10
obj.name = "Bob"
arr[0] = 99
obj["key"] = "value"

Valid assignment targets

• Identifiers: x = 1
• Property access: obj.prop = 1
• Index access: arr[0] = 1, obj["key"] = 1

Compound assignment operators

Jyro supports the following compound assignment operators, which combine an arithmetic operation with assignment:

Operator	Equivalent To
+=	x = x + value
-=	x = x - value
*=	x = x * value
/=	x = x / value
%=	x = x % value

var total = 0
total += 10        # total is now 10
total -= 3         # total is now 7
total *= 2         # total is now 14

Compound assignment operators work on all valid assignment targets:

Data.count += 1
arr[0] *= 2
