Maybe I'm just parsing it the wrong way, but could you get away with this restaurant name anywhere other Glasgow? And it's in the fashionable area of Finnieston, too!
How to Avoid eval When Parsing Arrays
eval turns input into execution. Use JSON instead.
A Percise Parser, by @remyporter.bsky.social:
Thomas worked for a company based in Germany which was looking to expand internationally. Once they started servicing other locales, things started to break. It didn't take long to track the problem down to a very "percise" numeric parser. handleInput( value ){ let value_ = value; if( value.substring( 0, 1 ) === '+' ){ value_ = value.substring( 1 ); } value_ = value_.split( '.' ).join( '' ); if( this.usePercisionIfPercentage && value_.indexOf( ',' ) >= 0 ) { const parsedPreValue = value_.split( ',' )[ 0 ]; const parsedCommaValue = parseInt( value_.split( ',' )[ 1 ], 10 ) < 10 ? parseInt( value_.split( ',' )[ 1 ], 10 ) * 10 : value_.split( ',' )[ 1 ].substring( 0, 2 ); if( parsedCommaValue === 0 ) { value_ = parseInt( parsedPreValue, 10 ); } else { const parsedValue = parseInt( parsedPreValue + parsedCommaValue, 10 ); value_ = parseInt( parsedValue, 10 ) / 100; } } // do stuff with value_ }
