`log` Universal Filter Jump to heading

Added in v0.11.0 An easy way to console.log anything from inside of a template file.

Syntax Liquid

{{ "My Title" | log }}

Syntax Nunjucks

{{ "My Title" | log }}

Syntax JavaScript

module.exports = function(data) {
  // Caveat: you have access to `console.log` here, so probably use that.
  return this.log("My Title");
}

is functionally the same as running console.log("My Title") inside of your template.

Added in v2.0.0

You can drop log in between any filter chain you already have and it will log the incoming data and pass it through to the next filter.
