Code Writer
With manipulation methods that accept a string
for the new code, it's possible to write text using a provided code-block-writer.
Using the writer is very useful because it will write code out using the indentation and newline settings of the project. It's also easier to use.
Example
functionDeclaration.setBodyText(writer =>
writer.writeLine("let myNumber = 5;")
.write("if (myNumber === 5)").block(() => {
writer.writeLine("console.log('yes')");
})
);
