0031【Edabit ★☆☆☆☆☆】【使用箭头函数】Using Arrow Functions

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:

javascript 复制代码

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

Examples

javascript 复制代码

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

Notes

Solutions

javascript 复制代码

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

TestCases

javascript 复制代码

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")
