'This error message is related to a version mismatch between Babel and the required version specified in your project's dependencies.
'Babel is a JavaScript transpiler that allows you to use next-generation JavaScript syntax in older browsers. It seems that your project requires Babel version 7.0.0-0, but the installed version is 6.26.3.
'To resolve this issue, you can try updating Babel to the required version. You can do this by running the following command in your terminal:
npm install babel@^7.0.0-0
'If you're using yarn, the equivalent command would be:
yarn add babel@^7.0.0-0
xxxxxxxxxx
npm install --save-dev @babel/core@^7.0.0-0 #Install latest babel version
# Solve this issue upgrading outdated version of Babel installed.
xxxxxxxxxx
Installing latest version of babel or the required version of babel might work for you

A function is a reusable set of statements to perform a task or calculate a value.
Functions can be passed one or more values and can return a value at the end of their execution.
In order to use a function, you must define it somewhere in the scope where you wish to call it.

function factorial(n) {
if (n == 0) {
return 1;
} else {
return factorial(n - 1) * n;
}

This happens sometimes due to bad behavior in npm and yarn.
When they do optimized package hoisting they don’t reliably satisfy
the peerDependencies that each package asked for.
It is very annoying.
Sometimes the problem fixes itself if you delete node_modules and try again,
sometimes you need to remove your package lock file and let it rebuild.
Or you can manually modify the package lock file.
