chore: Use ES6 to write functions

[ghost]

The 'json.js' file isn't referred, so remove it.

Use ES6 to write functions for 'm.read' and 'Object.keys.forEach' in 'build.js'.

Not sure exactly, maybe it's used to replace this

@ZYSzys Yes, you're right. But I can't remember where we needed the json Markdown helper in the first place … 🤔

So this file shouldn't be removed? Well……I didn't find anywhere to refer…… XD

It's indirectly referenced:

nodejs.org/build.js

Lines 158 to 161 in 2ca6dec

	.use(discoverHelpers({
	directory: 'scripts/helpers',
	pattern: /\.js$/
	}))
