// MAIN //

/**
* Tests if two arguments have the same type.
*
* ## Notes
*
* -   The function uses the `typeof` operator to test for the same type.
*
* @param {*} a - first input value
* @param {*} b - second input value
* @returns {boolean} boolean indicating whether two arguments have the same type
*
* @example
* var bool = isSameType( true, true );
* // returns true
*
* @example
* var bool = isSameType( 3.14, 3.14 );
* // returns true
*
* @example
* var bool = isSameType( {}, [] );
* // returns true
*
* @example
* var bool = isSameType( NaN, NaN );
* // returns true
*
* @example
* var bool = isSameType( 0.0, '0.0' );
* // returns false
