Previously, Lightning developers were limited to Salesforce’s own, less widely used Aura programming model to build Lightning Components.
There is no limit on the kinds of Web components developers might want to create using Lightning Web Components. Jacob Lehrbaum, vice president of developer relations at Salesforce, said one example might be a lookup function to check your credit score and mortgage rates at a real estate site.
“We call these experience components,” Lehrbaum told eWEEK. “Developers also get 70 base components like sliders so they can build these apps faster with less code, and then build and configure pages through point-and-click tools.”
