So basically i have already created the typing effect but i can only get the first string in the array to work. I want to write out all at the arrays in new lines using the typing effect.I have listed the JSX and CSS files below. I should also point out that this just part of a big project so trying to run this JSX and css wont work
import React from 'react';
import "./Content.css";
const content =()=>{
const message =["WELCOME TO MY WORLD","THIS IS MY WEBSITE","I AM AT YOUR SERVICE"];
let i =0 ;
for(i=0; i<message.length;i++){
return(
<div className='background'>
<h1 className="typewriter">
{message[i]}
</h1>
</div>
)
}
}
export default content;
background{
display: flex;
justify-content: center;
flex-wrap: wrap;
}
canvas{width: 60;
}
.typewriter {
text-align: center;
overflow: hidden;
border-right: .15em solid black;
color: white;
font-family: Courier New;
top:30%;
font-size: 40px;
white-space: nowrap;
letter-spacing: .30em;
animation:
typing 3.5s steps(30, end),
blink-caret .75s step-end infinite;
}
/* The typing effect */
@keyframes typing {
from { width:20% }
to { width: 50% }
}
@keyframes blink-caret {
from, to { border-color: transparent }
}

In the Layers panel, drop down the text layer properties. Click the Animate button and choose Opacity from the menu. In the new Animate controls, turn the Opacity down to 0%. Ensuring that the playhead is at the start of the clip, create a keyframe for the Range Selector Start property, then change the setting to 0%.
Could make it a class component like this:
class Typer extends React.Component {
static defaultProps = {
heading: '',
dataText: []
}
constructor(props) {
super(props);
this.state = {
text: '',
isDeleting: false,
loopNum: 0,
typingSpeed: 150
}
}
componentDidMount() {
this.handleType();
}
handleType = () => {
const { dataText } = this.props;
const { isDeleting, loopNum, text, typingSpeed } = this.state;
const i = loopNum % dataText.length;
const fullText = dataText[i];
this.setState({
text: isDeleting ? fullText.substring(0, text.length - 1) : fullText.substring(0, text.length + 1),
typingSpeed: isDeleting ? 30 : 150
});
if (!isDeleting && text === fullText) {
setTimeout(() => this.setState({ isDeleting: true }), 500);
} else if (isDeleting && text === '') {
this.setState({
isDeleting: false,
loopNum: loopNum + 1
});
}
setTimeout(this.handleType, typingSpeed);
};
render() {
return (
<h1>{ this.props.heading }
<span>{ this.state.text }</span>
<span id="cursor"/>
</h1>
);
}
}
ReactDOM.render(
<Typer
heading={'Things I want to type:'}
dataText={["WELCOME TO MY WORLD","THIS IS MY WEBSITE","I AM AT YOUR SERVICE"]}
/>,
document.getElementById('app')
);
@import url('https://fonts.googleapis.com/css?family=VT323');
body {
font-family: 'VT323', monospace;
background-color: #003B00;
padding: 1em 2em;
}
h1 {
color: #00FF41;
}
#cursor {
border-left: .1em solid #00FF41;
animation: blink .7s steps(1) infinite;
}
@keyframes blink {
50% {
border-color: transparent;
}
}

If you want to use hooks to accomplish this, you can do something like this:
(big thanks to @AliKlein for the inspiration)
const { render } = ReactDOM;
const { useState, useEffect } = React;
const CONSTANTS = {
DELETING_SPEED: 30,
TYPING_SPEED: 150,
}
function TypeWriter({ messages, heading }) {
const [state, setState] = useState({
text: "",
message: "",
isDeleting: false,
loopNum: 0,
typingSpeed: CONSTANTS.TYPING_SPEED,
});
useEffect(() => {
let timer = "";
const handleType = () => {
setState(cs => ({
...cs, // cs means currentState
text: getCurrentText(cs),
typingSpeed: getTypingSpeed(cs)
}));
timer = setTimeout(handleType, state.typingSpeed);
};
handleType();
return () => clearTimeout(timer);
}, [state.isDeleting]);
useEffect(() => {
if (!state.isDeleting && state.text === state.message) {
setTimeout(() => {
setState(cs => ({
...cs,
isDeleting: true
}))
}, 500);
} else if (state.isDeleting && state.text === "") {
setState(cs => ({
...cs, // cs means currentState
isDeleting: false,
loopNum: cs.loopNum + 1,
message: getMessage(cs, messages)
}));
}
}, [state.text, state.message, state.isDeleting, messages]);
function getCurrentText(currentState) {
return currentState.isDeleting
? currentState.message.substring(0, currentState.text.length - 1)
: currentState.message.substring(0, currentState.text.length + 1);
}
function getMessage(currentState, data) {
return data[Number(currentState.loopNum) % Number(data.length)];
}
function getTypingSpeed(currentState) {
return currentState.isDeleting
? CONSTANTS.TYPING_SPEED
: CONSTANTS.DELETING_SPEED;
}
return (
<h1>
{heading}
<span>{state.text}</span>
<span id="cursor" />
</h1>
);
}
let msgs = ["WELCOME TO MY WORLD","THIS IS MY WEBSITE","I AM AT YOUR SERVICE"];
render(<TypeWriter heading={"Things I want to type:"} messages={msgs} />, document.body);
@import url('https://fonts.googleapis.com/css?family=VT323');
body {
font-family: 'VT323', monospace;
background-color: #003B00;
padding: 1em 2em;
}
h1 {
color: #00FF41;
}
#cursor {
border-left: .1em solid #00FF41;
animation: blink .7s steps(1) infinite;
}
@keyframes blink {
50% {
border-color: transparent;
