# Error: $parse:lval
Trying to assign a value to a non l-value

    Trying to assign a value to a non l-value

## Description

Occurs when an expression is trying to assign a value to a non-assignable expression.

This can happen if the left side of an assigment is not a valid reference to a variable or property. E.g. In the following snippet `1+2` is not assignable.

    (1+2) = 'hello';
