Installation and usage
In browsers:
<script src="lodash.js"></script>
Using npm
:
npm install lodash
npm install -g lodash
npm link lodash
To avoid potential issues, update npm
before installing Lo-Dash:
npm install npm -g
In Node.js and RingoJS v0.8.0+:
var _ = require('lodash');
// or as a drop-in replacement for Underscore
var _ = require('lodash/lodash.underscore');
Note: If Lo-Dash is installed globally, run npm link lodash
in your project’s root directory before requiring it.
In RingoJS v0.7.0-:
var _ = require('lodash')._;
In Rhino:
load('lodash.js');
In an AMD loader like RequireJS:
require({
'paths': {
'underscore': 'path/to/lodash'
}
},
['underscore'], function(_) {
console.log(_.VERSION);
});
