How can normal JavaScript function be used in lightning component?
First, create a lightning application then get into the js helper class and place your java script function in that, your problem will be solved. Example: You can add a “normal” Javascript Function to your helper file. For example, if you are on a component named “foo”.
Share JavaScript Code
- Create JavaScript files that export code in the same folder as the component importing the code. Import the code using a relative path.
- Create a service component (library), which is a component folder that contains one or more JavaScript files that export code.
How can you share code between files?
Using ES5 syntax in Node means that the sharing of code between files is done with the ‘require’ and ‘module. exports’ statements. A ‘module’ in Javascript can be thought of as a container that holds related code which can then be exported to another file.
Is JavaScript required for Salesforce?
JavaScript has always been available to Salesforce developers, but with the appearance of Lightning, it is now a first-class language on the platform. That means it’s time for every Salesforce developer to learn JavaScript.
Where do we use JavaScript in Salesforce?

Can a lightning component be self contained in JavaScript?
You can build simple Lightning components that are entirely self-contained. However, if you build more complex applications, you probably want to share code, or even client-side data, between components. To reference a JavaScript library, upload it as a static resource and use a tag in your .cmp or .app markup.
How is the Lightning component framework used in Salesforce?
The Lightning Component framework uses Content Security Policy ( CSP) to impose restrictions on content. The main objective is to help prevent cross-site scripting ( XSS) and other code injection attacks. To use third-party APIs that make requests to an external (non-Salesforce) server or to use a WebSocket connection, add a CSP Trusted Site.
#Share JavaScript Code To share code between components, create an ES6 module and export the variables or functions that you want to share. An ES6 module is a JavaScript file that explicitly exports variables or functions that other modules can use. Modules make it easier to structure your code without polluting the global scope.
How are helper functions used in Lightning components?
Helper functions are local to a component, improve code reuse, and move the heavy lifting of JavaScript logic away from the client-side controller, where possible. You can build simple Lightning components that are entirely self-contained.
