Arguments

Param Type Details
expression string

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.
