Using the new code snippets feature in google chrome
I am using the code snippets in google chrome, so say I have a snippet file. check_consistency.js
I have a work around for when I'm running snippets a bunch of times on a site. I wrap my snippet code in a function and assign it to a global variable.
e.g.,
window.mySnippet = function (value) {
console.log(value.toUpperCase());
};
When I run this snippet I can now run
mySnippet('hello world');
-> "HELLO WORLD"
You still have to run the snippet once to load it into memory, but it's better than nothing.
