The\n * getter acts as a guard against chaining `length` directly off of an uninvoked\n * method assertion, which is a problem because it references `function`'s\n * built-in `length` property instead of Chai's `length` assertion. When the\n * getter catches the user making this mistake, it throws an error with a\n * helpful message.\n *\n * There are two ways in which this mistake can be made. The first way is by\n * chaining the `length` assertion directly off of an uninvoked chainable\n * method. In this case, Chai suggests that the user use `lengthOf` instead. The\n * second way is by chaining the `length` assertion directly off of an uninvoked\n * non-chainable method. Non-chainable methods must be invoked prior to\n * chaining. In this case, Chai suggests that the user consult the docs for the\n * given assertion.\n *\n * If the `length` property of functions is unconfigurable, then return `fn`\n * without modification.\n *\n * Note that in ES6, the function's `length` property is configurable, so once\n * support for legacy environments is dropped, Chai's `length` property can\n * replace the built-in function's `length` property, and this length guard will\n * no longer be necessary. In the mean time, maintaining consistency across all\n * environments is the priority.\n *\n * @param {Function} fn\n * @param {String} assertionName\n * @param {Boolean} isChainable\n * @namespace Utils\n * @name addLengthGuard\n */\n\nmodule.exports = function addLengthGuard(fn, assertionName, isChainable) {\n if (!fnLengthDesc.configurable) return fn;\n Object.defineProperty(fn, 'length', {\n get: function () {\n if (isChainable) {\n throw Error('Invalid Chai property: ' + assertionName + '.length.
