Tests:

  • 1MB string comparison

     
    const s1 = strings1MB[~~(strings1MB.length*Math.random())];
    const s2 = strings1MB[~~(strings1MB.length*Math.random())];
    const b = s1 === s2;

  • 2MB string comparison

     
    const s1 = strings2MB[~~(strings2MB.length*Math.random())];
    const s2 = strings2MB[~~(strings2MB.length*Math.random())];
    const b = s1 === s2;

  • 10MB string comparison

     
    const s1 = strings10MB[~~(strings10MB.length*Math.random())];
    const s2 = strings10MB[~~(strings10MB.length*Math.random())];
    const b = s1 === s2;

  • 10MB string comparison (equal)

     
    const s1 = strings10MB2[~~(strings10MB2.length*Math.random())];
    const s2 = s1 + "";
    const b = s1 === s2;
