javascript how do i get .data info within a function with forEach function?-CodePudding

playing around with foreach fuction atm, and trying to get .data out of it.

const foreachfunc = (data = null) => {
    data.forEach((element, index) => {
        console.log('element = '   element, 'index = '   index)
        let head = element.head
        console.log(head)
    });
};

const myarray = ["test1", "test2"]

foreachfunc(myarray)

okay so right now it outputs:

element = test1 index = 0
undefined
element = test2 index = 1
undefined

and it does makes sense since i haven't giving 'head' any data yet. But is it possible to give 'head' data within 'myarray'?

CodePudding user response：

Problem is with your array as it does not contain data that you are trying to access. check updated code below

const foreachfunc = (data = null) => {
    data.forEach((element, index) => {
        console.log('element = '   element.text, 'index = '   index)
        let head = element.head
        console.log(head)
    });
};

const myarray = [{head:"head1",text:"text1"},{head:"head2",text:"text2"}]

foreachfunc(myarray)
