Currently diving into the world of Angular 2 with TypeScript, finding it incredibly intriguing yet also a bit perplexing. The challenge lies in grasping how the code we write in TypeScript translates to ECMAScript when executed.
I've come across mentions of a transpiler, but haven't quite wrapped my head around its role in this process.
It's got me pondering: How exactly is this seamless functionality achieved?
There are a couple of methods to achieve this:
Dynamic transpilation (similar to how it's implemented in plunkr):
<script>
System.config({
transpiler: 'typescript',
typescriptOptions: { emitDecoratorMetadata: true },
packages: {
'app': {
defaultExtension: 'ts'
}
}
});
(...)
</script>
