isMethod

Test if an object has a specified method name.

Usage

var isMethod = require( '@stdlib/assert/is-method' );

isMethod( value, property )

Returns a boolean indicating if a value has a specified own method name.

function noop() { // Example function... } var value = { 'beep': noop }; var bool = isMethod( value, 'beep' ); // returns true bool = isMethod( value, 'toString' ); // returns false

Notes

Value arguments other than null or undefined are coerced to objects.

var bool = isMethod( 'beep', 'toString' ); // returns false

Property arguments are coerced to strings.

function noop() { // Example function... } var value = { 'null': noop }; var bool = isMethod( value, null ); // returns true value = { '[object Object]': noop }; bool = isMethod( value, {} ); // returns true

The function searches only own properties.

Examples

var isMethod = require( '@stdlib/assert/is-method' ); var bool = isMethod( { 'a': isMethod }, 'a' ); // returns true bool = isMethod( { 'a': 'b' }, 'a' ); // returns false bool = isMethod( { 'a': 'b' }, null ); // returns false bool = isMethod( {}, 'toString' ); // returns false bool = isMethod( null, 'a' ); // returns false bool = isMethod( void 0, 'a' ); // returns false bool = isMethod( { 'null': isMethod }, null ); // returns true bool = isMethod( { '[object Object]': isMethod }, {} ); // returns true
