Question

Mention some of the functions used in ember packages/ember run-time/lib and packages/ember metal/lib/utils.js ?

Answer 1

• None : Returns tur if argument is null or undefined
• Empty: Utility function constrains the rules on ember.none by returning false for empty string and empty arrays
• isArray: Use this to check whether the value is an array
• MakeArray: This function is used when you want a given object in an array
• Typeof: This is used to get the type of the passed argument
• Compare: Used to compare two objects of possibly different types
• isEqual: It checks whether the passed two arguments are logically equal
• inspect: While debugging this function is useful. For a given object it returns the string description
• Log_Binding:  Log binding is not a function but a Boolean function. If set true ember will log all the activity that is happening on the bindings
