React Conditional

React Conditional Rendering

conditional rendering is a technique used to render different content or components based on certain conditions.

This can be achieved using JavaScript expressions within your JSX code.

Here are a few ways to implement conditional rendering in React:

1.Using if Statements:

You can use regular JavaScript 'if' statements to conditionally 'render' content. This is typically done outside the return statement in the render method:

render() {
let content;
if (someCondition) {
content = <p>This content is rendered when someCondition is true.</p>;
} else {
content = <p>This content is rendered when someCondition is false.</p>;
}

return (
<div>
{content}
</div>
);
}

2.Using the Ternary Operator:

The ternary operator ('condition ? trueValue : falseValue') can be used for concise conditional rendering:

render() {
return (
<div>
{someCondition ? <p>True Content </p> : <p>False Content</p>}
</div>
);
}

3.Using Logical && Operator:

The logical AND ('&&') operator can be used for short-circuit evaluation to conditionally render content:

render() {
return (
<div>
{someCondition && <p>Rendered when someCondition is true</p>}
</div>
);
}

4.Using Conditional (ternary) Rendering in JSX:

You can use JSX itself to conditionally render components or elements. For example:

render() {
return (
<div>
{someCondition ? (
<p>Rendered when someCondition is true</p>
) : (
<p>Rendered when someCondition is false</p>
)}
</div>
);
}
