Flexible type checking including isUndefined, isNull, isBoolean, isNumber, isDate, isString, isRegExp, isArray, isArguments, isFunction and isObject.

Determines whether a value is of a specific type.

• .isUndefined( value )
• .isNull( value )
• .isBoolean( value )
• .isNumber( value )
• .isDate( value )
• .isString( value )
• .isRegExp( value )
• .isArray( value )
• .isArguments( value )
• .isFunction( value )
• .isObject( value )

var type = require( 'type-tool' );
if ( type.isFunction( value ) ) {
  // value is a function
}

Returns type name of value. Possible results are: 'undefined', 'null', 'boolean', 'number', 'date', 'string', 'regexp', 'array', 'arguments', 'function' and 'object'.

var type = require( 'type-tool' );
if ( type.name( value ) == 'array' ) {
  // value is an array
}

Returns type information of value including name and specific type flags.

var type = require( 'type-tool' );
var ti = type.get( [] ); // -> ti == { name: 'array', isArray: true }
ti = type.get( value );
if ( ti.isArray ) {
  // value is an array
}
else if ( ti.isFunction ) {
  // value is a function
}
else if ( ti.isNumber ) {
  // value is a number
}
