expression

Execute a JS expression in a context

Installation

Install with component(1):

$ component install ripplejs/expression

API

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
});

Properties
