    The deprecated escape() method computes a new string in which certain characters have been replaced by a hexadecimal escape sequence. Use encodeURI or encodeURIComponent instead.




    A string to be encoded.


    The escape function is a property of the global object. Special characteres are encoded with the exception of: @*_+-./

    The hexadecimal form for characters, whose code unit value is 0xFF or less, is a two-digit escape sequence: %xx. For characters with a greater code unit, the four-digit format %uxxxx is used.


    escape("abc123");     // "abc123"
    escape("äöü");        // "%E4%F6%FC"
    escape("ć");          // "%u0107"
    // special characters
    escape("@*_+-./");    // "@*_+-./"
