Benchmark: parse line2 - MeasureThat.net

Script Preparation code:



let i = 0

Tests:

split then equality
const iterations = 10000; const str = "int var = 1000;" const firstWord = str.split(" ")[0] let acc = "" for(let i = 0; i < iterations; i++){ switch(firstWord){ case "int": break case "float": break case "//": break case "uniform": break case "attribute": break case "struct": break default: break } }
check each time
const iterations = 10000; const str = "int var = 1000;" let acc = "" for(let i = 0; i < iterations; i++){ if(str.startsWith("int")){ } else if(str.startsWith("float")){ }else if(str.startsWith("//")){ }else if(str.startsWith("uniform")){ }else if(str.startsWith("attribute")){ }else if(str.startsWith("struct")){ }else if(str.startsWith("//")){ }else { } }
