How does lodash.truncate work?

lodash.truncate is a function from the Lodash library that takes a string as input, along with an optional options object that specifies the length to truncate to, as well as other options like the omission string to add at the end of the truncated string. By default, lodash.truncate will truncate the string to 30 characters and add an ellipsis ("...") at the end. However, you can customize this behavior by passing an options object with the desired properties. For example, you can set length to a different value and specify a custom omission string: javascript Copy code {{{{{{{ import { truncate } from 'lodash'; const str = 'The quick brown fox jumps over the lazy dog'; const truncatedStr = truncate(str, { length: 20, omission: '...', }); console.log(truncatedStr); // "The quick brown fo..." In this example, we use lodash.truncate to truncate the string str to 20 characters, and add an ellipsis ("...") at the end. The resulting truncated string is "The quick brown fo...". Internally, lodash.truncate uses String.prototype.slice to extract the substring of the input string that should be kept. If the string is truncated, it appends the omission string to the end of the truncated string. If the omission string is not provided, it defaults to "...".

import { truncate } from "lodash";

const str = "The quick brown fox jumps over the lazy dog";

const truncatedStr = truncate(str, {
  length: 10,
  omission: "***",
});

console.log(truncatedStr); // "The quick***"

In this example, we use lodash.truncate to truncate the string str to 10 characters, and add a custom suffix of three asterisks ("***") at the end. The resulting truncated string is "The quick***".
