There is a unique string generated from an external data source that I cannot manage. The system above me necessitates the IDs to adhere to this rule: "Field names should start with a letter and can solely consist of letters, numbers, or underscores ('_')".
In Typescript/Javascript (maybe utilizing lodash), what approach can be used to substitute all non-letter/digit/underscore characters in the string with an underscore?
let str = '8~3m_E!P$m%S^wx_-';
str.replace(/[\W]/gm, '_');
// output: 8_3m_E_P_m_S_wx__
Please note that the requirement specifying that field names must begin with a letter is not addressed in this code snippet. However, based on your question, it was assumed that you had already accounted for this rule.
