data_structures language_fundamentals

Instructions

Create a function that returns the given argument, but by using an arrow function.

An arrow function is constructed like so:

arrowFunc=(/*parameters*/)=>//code here

Examples

arrowFunc(3) // 3
arrowFunc("3") // "3"
arrowFunc(true) // true

Notes

• N/A

Solutions

// create your arrow function below
arrowFunc = (parameter) => parameter ;

TestCases

let Test = (function(){return {assertEquals:function(actual,expected){if(actual !== expected){let errorMsg = `actual is ${actual},${expected} is expected`;throw new Error(errorMsg);}}}
})();if(!(String(arrowFunc).includes('=>'))){Test.assertEquals(0,1,"Your code does not use an arrow function")
}Test.assertEquals(arrowFunc(3),3)
Test.assertEquals(arrowFunc("3"),"3")
Test.assertEquals(arrowFunc(true),true)
Test.assertEquals(arrowFunc("test"),"test")
