If null safety is critical for your application, we suggest that you take extra precautions [e.g. Applies a function against an accumulator and each value of the array (from left-to-right) to reduce it to a single value. then Lodash/Underscore might be the better option. Use Object.keys to get all the keys from the object. It's exposed on _ because previously, like Underscore, it was only exposed in the chaining syntax. Lowercases a given string. You are looking for flexibility without relying on an external library like lodash. "plugin:you-dont-need-lodash-underscore/compatible", // Native (works even with potentially undefined/null, like _.first), // Native (works even with potentially undefined/null), // output: {3: ["one", "two"], 5: ["three"]}, // Underscore/Lodash - also called _.contains, // output: { a1: { id: 'a1', title: 'abc' }, b2: { id: 'b2', title: 'def' } }, // output: { a1: { id: 'a1', title: 'abc' }}, // or also more universal and little slower variant of minBy. Removes the leading and trailing whitespace characters from a string. You signed in with another tab or window. Creates a lodash object which wraps value to enable implicit chaining. ❗Not in Underscore.js Creates a version of the function that will only be run after first being called count times.
