Can we pass props to a component that has the same name and value implicitly?
Example: Let's say that I have a variable called x: const x = 1; and I have a component that has a prop called x. Can I pass it this variable as value implicitly? like that: <div x/>?

Anti-pattern: Unconditionally copying props to state Because of this, it has always been unsafe to unconditionally override state using either of these lifecycles. Doing so will cause state updates to be lost.
There is no need to write that a prop is equal to true. Instead, you can just include the prop value, and it will be given the boolean value true when you use it in a component to which you pass it.
Press F2 and then type the new desired name and press Enter. All usages of the symbol will be renamed, across files.
Short answer: props are passed by reference. The reason it can be confusing: if you change the parent's state by hand (bad practice!), the object will change in the child component, too. But won't trigger re-render! (The child component won't "know" that its props has changed.)
Booleans can be passed implicitly to the component as @Ajay also pointed out in comments, like
<div x /> which is basically equivalent to
<div x={true} /> However, if your variable is something other than a boolean, then you need to write it like
<div x={x} /> Or if you have a number of such props, you can form an object like
const cmpProps = { x, y, foo, bar } and pass them using Spread attributes like
<Comp {...cmpProps} /> If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
