Parameters

ParamTypeDetails
expressionstring String expression to compile.

Returns

function(context, locals) a function which represents the compiled expression: - context – {object} – an object against which any expressions embedded in the strings are evaluated against (typically a scope object). - locals – {object=} – local variables context object, useful for overriding values in context. The returned function also has the following properties: - literal – {boolean} – whether the expression's top-level node is a JavaScript literal. - constant – {boolean} – whether the expression is made entirely of JavaScript constant literals. - assign – {?function(context, value)} – if the expression is assignable, this will be set to a function to change its value on the given context.
