# isSameValue > Test if two arguments are the same value.
## Usage ```javascript var isSameValue = require( '@stdlib/assert/is-same-value' ); ``` #### isSameValue( a, b ) Tests if two arguments `a` and `b` are the same value. ```javascript var bool = isSameValue( false, false ); // returns true bool = isSameValue( '', '' ); // returns true bool = isSameValue( {}, {} ); // returns false ``` In contrast to the strict equality operator `===`, the function distinguishes between `+0` and `-0` and treats `NaNs` as the same value. ```javascript var bool = ( 0.0 === -0.0 ); // returns true bool = isSameValue( 0.0, -0.0 ); // returns false bool = isSameValue( -0.0, -0.0 ); // returns true bool = ( NaN === NaN ); // returns false bool = isSameValue( NaN, NaN ); // returns true ```
## Notes - The function implements the [SameValue Algorithm][ecma-262-same-value-algorithm] as specified in ECMAScript 5.
## Examples ```javascript var isSameValue = require( '@stdlib/assert/is-same-value' ); var bool = isSameValue( true, true ); // returns true bool = isSameValue( true, false ); // returns false bool = isSameValue( 'beep', 'beep' ); // returns true bool = isSameValue( 3.14, 3.14 ); // returns true bool = isSameValue( null, null ); // returns true bool = isSameValue( 0.0, 0.0 ); // returns true bool = isSameValue( -0.0, 0.0 ); // returns false bool = isSameValue( NaN, NaN ); // returns true bool = isSameValue( {}, {} ); // returns false bool = isSameValue( [], [] ); // returns false bool = isSameValue( isSameValue, isSameValue ); // returns true ```
