// without escapeRegexStr, the test fails.
const regex1 = new RegExp(sourceStr)
console.log(regex1.test('Unicorn (white): $1.00')) // ⇒ false

// with escapeRegexStr, it succeeds.
const regex2 = new RegExp(escapeRegexStr(sourceStr))

Imports

All the JSBits functions works in strict mode and are compatible with:

• ES5 browsers, through the jQuery $.jsbits object or the global jsbits.
• ESM Bundlers, like webpack and Rollup.
• ES modules for modern browsers or NodeJS with the --experimental-modules flag.
• CommonJS modules of NodeJS, jspm, and others.
• Babel and TypeScript, through ES Module Interop.

Please see the Distribution Formats in the JSBits README to know about all the variants.
