I have a list of expenses, I want to create a html code to iterate over all the expenses and show their name. I am not working with the DOM, I literally want to save the html code in a variable, so I can generate a pdf file with it.
This is what I tried: lets say I have this array
const spents = [{expenseName: "Pizza"},{expenseName: "Home"}]
const testHtml = () => {
for(let i of spents) {
const title = `<h1>${i.expenseName}</h1>`
}
}
testHtml()
This is the result I want, something like:
htmlResult = "
<h1>${i.expenseName}</h1> <h1>${i.expenseName}</h1>"
by the way, This is for a react native app.
I think this will work for you.
const spents = [{expenseName: "Pizza"},{expenseName: "Home"}]
const testHtml = () => {
let title = '';
for(let i of spents) {
title += `<h1>${i.expenseName}</h1>`
}
return title;
}
testHtml()
You could use Array.prototype.reduce().
const spents = [{
expenseName: "Pizza"
}, {
expenseName: "Home"
}];
const result = spents.reduce((prev, curr, index) => index === 0 ? curr.expenseName : `<h1>${prev}</h1> <h1>${curr.expenseName}</h1>`, '');
document.body.append(result);
