Why Escape JavaScript Strings?
Strings inserted into JavaScript source need correct escaping to avoid syntax errors, broken output, or unintended behavior. Escaping is particularly useful when embedding user input, API payloads, HTML snippets, or configuration values inside JavaScript variables and templates.
