Also update the PRESUBMIT linter configuration to make sure it actually runs the linter when updating ESLint. Otherwise, it would not properly do the full linter check.

ESLint Scope
ESLint Scope is the ECMAScript scope analyzer used in ESLint. It is a fork of escope.
Usage
Install:
npm i eslint-scope --save
Example:
var eslintScope = require('eslint-scope');
var espree = require('espree');
var estraverse = require('estraverse');
var ast = espree.parse(code);
var scopeManager = eslintScope.analyze(ast);
var currentScope = scopeManager.acquire(ast); // global scope
estraverse.traverse(ast, {
enter: function(node, parent) {
// do stuff
if (/Function/.test(node.type)) {
currentScope = scopeManager.acquire(node); // get current function scope
}
},
leave: function(node, parent) {
if (/Function/.test(node.type)) {
currentScope = currentScope.upper; // set to parent scope
}
// do stuff
}
});
