Execute a JS expression in a context
Install with component(1):
$ component install ripplejs/expression
var exp = new Expression("one + (two * one)");
var result = exp.exec({
two: 10,
one: 2
});
assert(result === 22);Create a new Expression, passing in a string.
var exp = new Expression("one + (two * one)");Execute this expression using a given context. For example, this expression
above depends on the variables one and two. So we can pass in an object
with these properties.
var result = exp.exec({
two: 10,
one: 2
});Returns the properties used in the expression
