{{alias}}( value ) Tests if a value is an array-like object containing only NaN values. Parameters ---------- value: any Value to test. Returns ------- bool: boolean Boolean indicating whether value is an array-like object containing only NaN values. Examples -------- > var bool = {{alias}}( [ NaN, NaN, NaN ] ) true > bool = {{alias}}( [ NaN, 2 ] ) false {{alias}}.primitives( value ) Tests if a value is an array-like object containing only primitive NaN values. Parameters ---------- value: any Value to test. Returns ------- bool: boolean Boolean indicating whether value is an array-like object containing only primitive NaN values. Examples -------- > var bool = {{alias}}.primitives( [ NaN, new Number( NaN ) ] ) false > bool = {{alias}}.primitives( [ NaN, NaN, NaN ] ) true {{alias}}.objects( value ) Tests if a value is an array-like object containing only number objects having NaN values. Parameters ---------- value: any Value to test. Returns ------- bool: boolean Boolean indicating whether value is an array-like object containing only number objects having NaN values. Examples -------- > var bool = {{alias}}.objects( [ new Number( NaN ), new Number( NaN ) ] ) true > bool = {{alias}}.objects( [ NaN, new Number( NaN ), new Number( NaN ) ] ) false > bool = {{alias}}.objects( [ NaN, NaN, NaN ] ) false See Also --------
