In non-supporting environments, the value is `null`.\n\n-   When an object needs to be converted to a primitive value, JavaScript runtimes look for a `[ToPrimitiveSymbol]()` method on the object. If the method exists, JavaScript runtimes call the method with a `hint` string argument (one of `'number'`, `'string'`, or `'default'`) indicating the preferred type of the primitive value to be returned.\n\n    -   If the hint is `'number'`, the method should return a number.\n    -   If the hint is `'string'`, the method should return a string.\n    -   If the hint is `'default'`, the method can return either a number or a string.\n\n-   If an object does not have a `[ToPrimitiveSymbol]()` method, JavaScript runtimes use the default type conversion algorithm by calling `valueOf()` and/or `toString()` methods.\n\n</section>\n\n<!-- /.notes -->\n\n<!-- Package usage examples. -->\n\n<section class=\"examples\">\n\n## Examples\n\n<!-- eslint-disable no-invalid-this -->\n\n<!-- eslint no-undef: \"error\" -->\n\n```javascript\nvar defineProperty = require( '@stdlib/utils-define-property' );\nvar Number = require( '@stdlib/number-ctor' );\nvar ToPrimitiveSymbol = require( '@stdlib/symbol-to-primitive' );\n\nfunction CustomObject( value ) {\n    if ( !(this instanceof CustomObject) ) {\n        return new CustomObject( value );\n    }\n    this._value = value;\n    return this;\n}\n\nfunction toPrimitive( hint ) {\n    var value = this._value;\n    if ( hint === 'string' ) {\n        return 'CustomObject: ' + value;\n    }\n    if ( hint === 'number' ) {\n        return value;\n    }\n    // Default hint:\n    return value;\n}\n\ndefineProperty( CustomObject.prototype, ToPrimitiveSymbol, {\n    'configurable': false,\n    'enumerable': false,\n    'writable': false,\n    'value': toPrimitive\n});\n\nvar obj = new CustomObject( 42 );\n\nconsole.log( String( obj ) );\n// => 'CustomObject: 42'\n\nconsole.log( Number( obj ) );\n// => 42\n\nconsole.log( obj + 10 );\n// => 52\n```\n\n</section>\n\n<!-- /.examples -->\n\n<!-- Section to include cited references.
