So with the understanding of theindexOfmethod, we can make use of it to check if the string contains spaces by passing a whitespace string to the method. Since the method returns an index when a whitespace exists, we can check if the value is greater than or equal to zero which returns...

Use a function here to control how the resulting module name string will look like. It's useful if you for instance want to add a custom prefix to certain imports. Apart from the standardpathToCurrentFileandpathToImportedModulevalues passed in to all configuration functions, this method is als...

Here's what happens when this flag is on: new Array(1, 2, 3) or Array(1, 2, 3)→ [ 1, 2, 3 ] new Object()→ {} String(exp) or exp.toString()→ "" + exp new Object/RegExp/Function/Error/Array (...)→ we discard the new Conditional compilation You can use the --...
DANGER: will not check if the name is redefined in scope. An example case here, for instance var q = Math.floor(a/b). If variable q is not used elsewhere, UglifyJS will drop it, but will still keep the Math.floor(a/b), not knowing what it does. You can pass pure_funcs: [ ...

The rules and filters are executed in the same order as they’re defined, so if you want to trim a string for whitespace first and then check if it has any value, you have to define.trim()before.required(). Datalize will then create an object (available as.formin the wider context ...
