Module: rgjs/utils

RGJS6 Utils module.

Methods

<static> evalf(str [, bindTo] [, args])

Eval() may be bad, but we can at least try to do it as efficiently as possible. Note: If provided with a string without () and it turns out to be a function, evalf() will be able to run it more efficiently.

Parameters:
Name Type Argument Description
str string

The string to be evaluated. May also be a function.
bindTo object <optional>

Optional. The object the function call will be bound to ('this' will be whatever 'bindTo' is).
args * <optional>
<repeatable>

Optional. Arguments to be passed.
Examples
// Optimized: results in alert.apply(null, 'hello');
rgjs.utils.evalf('alert', null, 'hello');
// Non-optimized: results in eval('alert()');
rgjs.utils.evalf('alert()');
// Function
rgjs.utils.evalf(function(){ alert(); });
