如何在Javascript中将驼峰式转换为蛇形? [英] How to convert camelcase to snake case in Javascript?

问题描述

我想使用TypeScript将驼峰式的字符串转换为蛇形.

I want to convert a string of that is in camel case to snake case using TypeScript.

请记住，蛇案"是指指的是一种格式样式，其中每个空格都用下划线(_)字符替换，并且每个单词的首字母都用小写字母表示.

Remember that the "snake case" refers to the format style in which each space is replaced by an underscore (_) character and the first letter of each word written in lowercase.

示例:fieldName到field_name应该是有效的转换，但是FieldName到Field_Name无效.

Example: fieldName to field_name should be a valid conversion, but FieldName to Field_Name is not valid.

推荐答案

const camelToSnakeCase = str => str.replace(/[A-Z]/g, letter => `_${letter.toLowerCase()}`);
