# isMethodIn > Test if an object has a specified method name, either own or inherited.
## Usage ```javascript var isMethodIn = require( '@stdlib/assert/is-method-in' ); ``` #### isMethodIn( value, property ) Returns a `boolean` indicating if a `value` has a specified method name, either own or inherited. ```javascript var value = { 'beep': 'boop' }; var bool = isMethodIn( value, 'toString' ); // returns true bool = isMethodIn( value, 'beep' ); // returns false bool = isMethodIn( value, 'bap' ); // returns false ```
## Notes - The function does **not** throw when provided `null` or `undefined`. Instead, the function returns `false`. ```javascript var bool = isMethodIn( null, 'toString' ); // returns false bool = isMethodIn( void 0, 'toString' ); // returns false ``` - Value arguments other than `null` or `undefined` are coerced to `objects`. ```javascript var bool = isMethodIn( 'beep', 'toString' ); // returns true ``` - Non-symbol property arguments are coerced to `strings`. ```javascript function noop() { // Example function... } var value = { 'null': noop }; var bool = isMethodIn( value, null ); // returns true value = { '[object Object]': noop }; bool = isMethodIn( value, {} ); // returns true ```
## Examples ```javascript var isMethodIn = require( '@stdlib/assert/is-method-in' ); var bool = isMethodIn( {}, 'toString' ); // returns true bool = isMethodIn( { 'a': 'b' }, 'a' ); // returns false bool = isMethodIn( { 'a': 'b' }, 'c' ); // returns false bool = isMethodIn( { 'a': 'b' }, null ); // returns false bool = isMethodIn( null, 'a' ); // returns false bool = isMethodIn( void 0, 'a' ); // returns false bool = isMethodIn( { 'null': isMethodIn }, null ); // returns true bool = isMethodIn( { '[object Object]': isMethodIn }, {} ); // returns true ```
